Reworks the portal consolidation from #3046, keeping its model — portal elements registered on the editor, themed roots for foreign targets — and changing how it is named and wired. Naming: one stem, `portalElement`, from `editor.registerPortalElement` and `mount(el, { portalElement })` through `resolvePortalElement`, `usePortalElement` and `PortalElementOverride` to the `portalElement` prop on every popover, menu and select. `portalRoot`, `portalTarget`, `portalContext` and `editorPortal` are gone. Where a forwarded prop and the ambient element coexist they are `portalElementProp` and `portalElement`. Theming: `ThemedRootProps` is replaced by a single `applyThemedRoot(element)` on `BlockNoteViewContext`, composed from the base classes and whatever the UI library adds. The mantine wrapper keeps base's `applyThemeVariables` ref for the editor container and passes the same function down for portal roots, so `BlockNoteTheme.ts` is untouched. Plumbing: the default portal element is derived in `usePortalElement` from the editor's own container, so `BlockNoteViewContainer` needs no state, no merged refs and no provider wrapper. `PortalElementOverride` creates its themed root directly and mounts it in a layout effect, replacing a `createPortal` of an empty div, a ref/state round-trip and a `closest(".bn-root")` read during render.

…aries Inside a component that receives a `portalElement` prop, `portalElement` now means that prop, and the surrounding default from `usePortalElement` takes the qualified name. Reads more directly, and keeps the props destructures on one line as they are on the base branch.

BREAKING: `editor.mount(element, { portalTarget })` loses its options
argument. The option decided where `editor.portalElement` was appended, and
that element no longer exists; it had already been reduced to an alias for
`registerPortalElement`, which callers can call directly and explicitly:
editor.mount(element);
editor.registerPortalElement(someContainer);
Only needed when floating UI renders outside the editor's DOM tree — UI next
to the contenteditable already counts as within the editor.
`portalRoot` is now required on `Menu.Root`, `Popover.Root` and the toolbar select. The UI-library adapters never read the editor's context, so they cannot fall back to it themselves; making the prop required lets the compiler enforce what was a convention. Call sites pass the ambient element as-is — `null` before the editor has mounted — instead of coercing it to `undefined`. What each adapter does with `null` follows its library, so none of them portal to the document body: - shadcn passes it through: Base UI waits for a container. - ariakit toggles `portal` off: it renders inline until there is one (Ariakit appends a fresh div to the body for null and undefined alike). - mantine already rendered inline on a falsy value. The shadcn tooltips (`ToolbarButton`, `Badge`) keep reading the ambient element through `useEditorPortalElement`. That is the one documented exception: mantine and ariakit tooltips render inline and would ignore a passed element, so a prop would buy nothing there.

`vp run build` typechecks example projects that lint doesn't cover: the three `SettingsSelect` copies render a `Toolbar.Select` without the now required prop. They sit inside `BlockNoteView`, so they read the ambient element and pass it. Also drops the last `?? undefined` on a portal value: the shadcn `Badge` tooltip passes the element as-is, like `ToolbarButton` already does, so nothing falls back to the body.

preventFocusOnOpen based on useUIMode() === "mobile", preserving editor focus
when the mobile popover opens. Add a touch regression test verifying that
opening the mobile popover does not blur the editor or dismiss the on-screen
keyboard.
In `@packages/ariakit/src/popover/Popover.tsx`:
- Line 61: Update Popover and ToolbarSelect to honor preventFocusOnOpen instead
of discarding it: thread the prop from Popover to PopoverContent, set
AriakitPopover autoFocusOnShow to the inverse value, and pass it directly to
AriakitSelectPopover. Add mobile regression coverage for both surfaces, covering
preservation of focus and the editor keyboard.
In `@packages/react/src/editor/portalElements.ts`:
- Line 7: Update the portal target contract around PortalElement,
resolvePortalElement, and PortalElementOverride so documented null targets
resolve to document.body and mount correctly, or remove the null documentation
and consistently document document.body as the required replacement. Keep the
public type, resolution behavior, and context value aligned so no detached root
is exposed for a null target.

Menus now portal out of the toolbar, side menu and table handle that open them, so rules scoped on those ancestors (`.bn-toolbar .mantine-Menu-item`, `.bn-side-menu .mantine-Menu-dropdown`, ...) stopped applying: 14px items, a missing min-width, an ariakit gap on every popover. Scope on the dropdowns' own classes instead, and keep the ariakit gap for form popovers only. The e2e drag-handle menu selector no longer assumes nesting either.
Every menu, popover and form a floating component (toolbar, side menu, table handle, ...) opens now portals into a zero-size anchor next to that component, inside the wrapper floating-ui positions. So they share its stacking context and visibility (the ariakit colors submenu paints above the drag handle without a z-index override; ariakit and shadcn dropdowns hide with their toolbar instead of staying orphaned when it scrolls away), follow it when `portalElements` relocates it, and, for the mobile toolbar, sit outside its scroll strip, which iOS WebKit would otherwise not paint. `GenericPopover`'s closing snapshot must ignore the anchor's holder, or a popover whose children are already gone would snapshot an empty wrapper and vanish instead of fading out. The adapter-private contexts in ariakit and shadcn are renamed so they no longer share a name with the react package's context.
Mantine's `useFocusTrap`, armed once focus was within the toolbar, moved focus back into the toolbar a tick after a menu or form opened. With those now portalled next to the toolbar rather than inside it, that stole focus from the link form's URL field (0 ms clicks in e2e, and always for the link toolbar's Edit button). Tab now moves through the buttons and on, as in the other skins. The color menu's deferred `editor.focus()` existed only to work around the trap.
Mounting schedules an update from an effect that can commit after `act` has returned. On Linux WebKit whether it does varies from mount to mount, so the setup measured second sometimes counted one commit fewer or more than the baseline and the comparison failed (CI's webkit shard, 1 of 3 runs locally in Docker). Wait until no commit has landed for 50 ms before reading the counts, at mount and after the parent re-render, so every mount is measured once things have settled.
`usePortalElement` fell back to the editor's `bn-container`, which is the editor element's parent in the default layout but not when a layout renders `BlockNoteViewEditor` itself: there the container may also hold a sidebar, and the table's extend button, sized to the table's full width, escaped the editor's scrolling pane and painted over the sidebar while the table stayed clipped. Fall back to the editor element's parent, as `mount()` did before: floating UI clips and scrolls with the editor, and `portalElements` remains the way to escape.
`PortalElement` is `HTMLElement | string` and `PortalElementOverride` takes `HTMLElement | undefined`, but two doc comments still promised that `null` means `document.body`. Nothing accepts it any more.
A view rendered inside another view's floating UI (the comments composer, an editor in a custom block's popover) inherited the outer view's portal anchor or override through context. That element is registered with the outer editor only, so the nested editor's own menus and popovers counted as outside it for isWithinEditor and the focus tracking built on it. BlockNoteViewContainer now resets the portal element for its subtree to the editor's own default.
When set, the UI library must not move focus into the surface when it opens; an input inside that asks for focus itself still gets it.
The link form tests now run for mantine, ariakit and shadcn: each skin's popover decides on its own how the URL field takes focus. The per-skin screenshot tests also wait for the link toolbar before comparing, since a missing toolbar stays within the 2% screenshot tolerance.

Summary
The portal-element layer of the mobile stack: how BlockNote's floating UI (toolbars, menus, popovers, forms) decides where in the DOM it renders. It reworks the portal consolidation from #3046 and #3054 (both now superseded by this PR, with their commits in its history), then fixes what the consolidation broke on desktop.
Stacked on
mobile-toolbar-demo(#2939); the layers above are #3028 → #3031 (stack #3056). Only this layer's own commits are the diff.What ships
One vocabulary, two concepts.
portalElementeverywhere:PortalElement,portalElements,resolvePortalElement,usePortalElement,PortalElementOverride,editor.registerPortalElement/unregisterPortalElement, and theportalElementprop on every adapter popover, menu and select (wasportalRoot). The themed root (.bn-root) is a single function,applyThemedRoot(element), onBlockNoteViewContext.Where floating UI renders, top to bottom:
bn-containerin the default layout; the element you renderBlockNoteViewEditorinto underrenderEditor={false}). This is whatmaindid. An earlier revision of this PR used thebn-containerinstead; the docs demo showed why that is wrong: with the editor in a scrolling pane next to a sidebar, the table extend button escaped the pane and painted over the sidebar while the table stayed clipped. Floating UI clips and scrolls with the editor; escaping is whatportalElementsis for.portalElementsonBlockNoteView(globaldefaultor per component) and a controller'sportalElementprop redirect a floating component elsewhere, viaPortalElementOverride, which mounts a themed root inside the target and registers it with the editor so focus inside it still counts as focus within the editor.PortalElementAnchor. They share the wrapper's stacking context and visibility (the ariakit colors submenu paints above the drag handle without a z-index override; ariakit and shadcn dropdowns hide with their toolbar instead of staying orphaned when it scrolls away), they follow the wrapper underportalElements, and for the mobile toolbar they sit outside its scroll strip, which iOS WebKit would otherwise not paint. Adapters keep a requiredportalElementprop.Desktop fallout of portalling, fixed here. Portalling menus out of the toolbar, side menu and table handle broke three things: CSS scoped on the opener (
.bn-toolbar .mantine-Menu-item,.bn-side-menu .mantine-Menu-dropdown, …) stopped applying, so menu items grew and the drag-handle menu lost its min-width; the e2e drag-handle selector assumed nesting; and Mantine'suseFocusTrapon the toolbar, armed once focus was within it, pulled focus back into the toolbar a tick after a form opened, so the link form's URL field lost focus (always for the link toolbar's Edit button, and for 0 ms synthetic clicks in e2e). Styles are rescoped on the dropdowns' own classes, the selector matches the menu by class, and the trap is gone: Tab moves through the buttons and on, as in the other skins. The color menu's deferrededitor.focus()existed only to work around the trap.GenericPopover's closing snapshot ignores the anchor's holder, otherwise a popover whose children are already gone would snapshot an empty wrapper and vanish instead of fading out.
Behaviour changes (release notes)

ToolbarButtonnor turning Ariakit's autofocus off on the popover fixes it; the composite toolbar's own focus handling is the likely cause.Changes since the first review round
BlockNoteViewrendered inside another view's floating UI (the comments composer, an editor in a custom block's popover) inherited the outer view's anchor or override through context; that element is registered with the outer editor only, so the nested editor's own menus and popovers counted as outside it forisWithinEditorand the focus tracking built on it.BlockNoteViewContainernow wraps its content in an internalPortalElementReset. Pinned inportalElements.test.tsx(red without the wrapper).preventFocusOnOpencontract written out once onToolbarSelectinComponentsContext, the Menu type points to it: the UI library must not move focus into the surface when it opens; an input inside that asks for focus itself still gets it. (The popover no longer takes the prop at all, see fix(ui): commit popover forms through submit, not a key handler #3030.)linkToolbar.test.tsxnow runs the create and edit flows for mantine, ariakit and shadcn. Reason: the ariakit create flow was broken on the stack while CI stayed green, because the skin screenshot tests use the global 2% pixel tolerance and the link toolbar is about 1% of the frame, so "no link, no toolbar" compared equal to the baseline. The ariakit, shadcn and theming screenshot tests now wait for.bn-link-toolbarbefore comparing.PortalElementOverridethat an earlier revision carried here moved up to fix(ui): commit popover forms through submit, not a key handler #3030, where it is red-first (the ariakit mobile link flow); on this layer alone only its own pin test could see it.The "Known follow-ups" above are outdated on one point: the ariakit mobile link flow is fixed in #3030.
