`handleKeyPress` returned `true` after dispatching the synthesized Enter whether or not a keymap handler handled it. For an unhandled Enter that made prosemirror-view cancel the browser default, dropping the key. Return the keymap result instead; the `beforeinput` path keeps claiming the event, as it already prevented the default.
Chromium's IME path can deliver Enter as a beforeinput insertText with a newline instead of insertParagraph. That fell through the Android Enter handling into the same DOM-diff corruption it exists to prevent. A newline insertText is now handled as Enter. The android e2e case drives it through a CDP IME composition commit.
…mounts useVirtualKeyboard publishes the --bn-vv-* properties on <html>. They are page-level and shared by every mounted editor, so a count of mounted hooks decides when they go: the last one out removes them. Left behind, they pinned a bn-scroll-container to the keyboard-open height after a client-side navigation to a page without an editor.
Below that iOS Safari zooms the page on focus. Mantine has a coarse-pointer rule for it, the ariakit and shadcn inputs are 16px already; this pins all three.
…desktop exclude The z-index pin passed vacuously when the submenu did not cover the handle. The desktop browser instances' exclude replaces vitest's defaults, so the list is built from them, once, as DESKTOP_EXCLUDE.

The toolbar's show state was recomputed only on selection and content changes, and reset only by a pointerdown inside the editor or a drag. A blur left it as it was, and ProseMirror keeps its selection across a blur. On a phone, tapping the page away from the editor closed the keyboard, the mobile controller unmounted, and the desktop controller mounted with the stale state and showed the desktop toolbar over a blurred editor. Desktop never showed it because the desktop popover's outside-press dismiss resets the store, but that only runs while it is mounted. The extension now subscribes to focus changes with the editor's UI included (toolbar buttons and popover inputs still count as focused, and the event fires once a handoff has settled): focus leaving resets the state, focus returning re-evaluates it unless a press or drag is in progress. Known edge: with focus inside the toolbar, scrolling the selection out of view hides the toolbar and the browser drops that focus, so the toolbar is gone until the next selection change; the floating-menu test accepts that.
…her unmounts The tallest viewport height seen, the stand-in for "keyboard closed", lived on for the next editor after the last one unmounted (review finding on #3031). It is cleared together with the --bn-vv-* properties, so an editor mounted after a client-side navigation starts from what it measures.
iOS Safari delivers a tap as a hover first: one mousemove straight to the tap point, then the click, and WebKit drops that click when the hover changes the page. The side menu's document mousemove handler looked up the block under the pointer for any target inside the editor's UI too, found none under the mobile toolbar and hid a shown side menu, so every toolbar button and menu item needed two taps whenever the side menu was showing. A move whose target is BlockNote UI outside the editor content (a toolbar, a menu, the side menu itself) now leaves the state as it is; on desktop that means hovering the formatting toolbar no longer moves or hides the side menu. mobileToolbar.test.tsx pins it (red before).
#2912 made block and inline content node views ignore every DOM mutation outside their content DOM and every attribute mutation, to stop the Dark Reader re-render loop (#2818). That also hid the browser's native paragraph split from ProseMirror: on Android and iOS prosemirror-view leaves Enter to the browser and reads the split back from the DOM, and the new paragraph lands next to the content DOM, so it was never read. On iOS the 200ms fallback split the document while the stray paragraph stayed in the block, rendered next to the text by the flex block content; on Android Enter, Backspace and Delete broke (#3001). Dark Reader writes attributes only: inline style declarations starting with --darkreader and data-darkreader-* attributes. Ignore exactly those and let everything else reach ProseMirror.
… into mobile/android-enter
It worked around a symptom of #2912's node view mutation filter, which kept prosemirror-view from reading the browser's native paragraph split on Android and iOS; the Dark Reader-only filter merged before this fixes the cause. Measured on the android e2e instance with that filter: the only case the interception still covered was an Enter keypress on a selection across blocks, which prosemirror-view's own keypress handler turns into a no-op. A rare pattern, accepted as a known gap (also a no-op with Gboard on a Fairphone 5) rather than kept as a workaround that reaches into prosemirror-view internals. The two remaining androidEnter tests pin prosemirror-view's DOM read, which went red under #2912's filter; the cross-block case in keyboardhandlers is skipped on android with the reason.
…ontent DOM Defining ignoreMutation replaces prosemirror-view's default, which ignores every mutation but the selection in a node view without a content DOM. The narrow filter answered "read it" there, so the image block's own DOM changes during a resize drag were read back, which reset the node selection and copied nothing (copypaste "Images should keep props": red in CI and in Docker without this, green with it). #2912 had kept that default explicitly; this restores it while everything else stays as before #2912.
… into mobile/android-enter
WebKit with an iPhone UA makes prosemirror-view take its iOS input paths: Enter is left to the browser and the native split is read back from the DOM with a 200ms fallback. That path broke under #2912's node view mutation filter and shipped in 0.53 as a stray paragraph in the block after Enter; the android instance cannot reach it. The Enter test now also asserts that no block content keeps a second inline-content child, which is red on this instance with the old filter and green with the Dark Reader-only one. Playwright's WebKit leaves maxTouchPoints at 0 for hasTouch, so the setup stubs it to 5, the one stub of the instance; the iframe is sized like android. Not emulated: iOS Safari's tap-as-hover, the soft keyboard, focus and zoom.
Chromium drops Emulation.setTouchEmulationEnabled whenever Page.captureScreenshot runs with captureBeyondViewport: true, which Playwright sends for every capture that does not fit the viewport and, on an isMobile context, for every element screenshot; Playwright arms touch once per session and never re-arms it (microsoft/playwright#42607). The comments blamed iframe-element screenshots and elements taller than the viewport. A checked-in repro prints the drop per screenshot call and over raw CDP.
The repro lives in microsoft/playwright#42607; the comment points there.
…at the top overscroll-behavior: contain on .bn-scroll-container kept the document from rubber-banding under the pinned container, but it also stopped the overscroll at the top from reaching the document, which is what the browser's pull-to-refresh needs; on iOS Safari the page could no longer be refreshed. The containment now applies to the y axis only once the container has scrolled: useVirtualKeyboard marks it with data-bn-scrolled from a capture-phase scroll listener while scrollTop is above 0. Checked on the iOS simulator: a pull from the top reloads, a drag past the bottom leaves the page in place as before. scrollContainer.test.tsx pins the computed overscroll-behavior-y per scroll position (red before).

Top of the stack, on #3030. Fixes #3001 (Enter on Android) and the "two columns after Enter" on iOS, through #3062.
The bug
On Android, prosemirror-view deliberately ignores Enter keydowns (the IME reports composing keys as keyCode 229, so key identity can't be trusted), lets the browser split the paragraph and reads the result back from the DOM; on iOS it does the same with a 200 ms fallback. Since #2912 (0.53) BlockNote's node views ignored every mutation outside their content DOM, and the browser's new paragraph lands next to the content DOM, so the split was never read. On Android that showed as Enter inserting a space, doing nothing, or breaking tables (#3001). On iOS the fallback split the document while the stray paragraph stayed in the block, rendered next to the text by the flex block content.
The fix
#3062 (merged into this layer, under review on main) replaces the blanket filter with one that ignores only what Dark Reader writes: attributes named
data-darkreader*and inlinestylevalues containing--darkreader, measured with Brave and Dark Reader on the code block and toggle examples. Everything else reaches ProseMirror again, as before #2912; a node view without a content DOM keeps prosemirror-view's own default of ignoring all but the selection (the image block's resize drag otherwise reset the node selection and broke copying it, see #3062).An earlier revision of this layer worked around the symptom by intercepting Enter on Android (
beforeinputandkeypress) and running the keymap chain directly. With the filter fixed, the only case the interception still covered was an Enter keypress on a selection across blocks, which prosemirror-view's own keypress handler turns into a no-op (also with Gboard on a Fairphone 5). That is accepted as a known gap for a rare pattern rather than kept as a workaround that reaches into prosemirror-view internals; the interception is gone.Tests
androidEnter.test.tsx: a keyboard-delivered Enter and a CDP-driven IME newline commit, both pinning prosemirror-view's DOM read; red under fix: ignore useless block/inline content mutations (BLO-1224) #2912's filter. The cross-block case,keyboardhandlers"Enter when selection is not empty", is skipped on the android instance with the reason next to it.beforeinput: insertParagraph, AOSP LatinIME sends 229 plus a real keydown; both take the DOM-read path. The device suite that made the discovery is parked onmobile/emulator-layer(test(device): local emulator layer — real Chrome/Gboard as normal CI #3034).Also on this layer (release review, 6 and 7 September)
FormattingToolbarextension). Itsshowstate was recomputed only on selection and content changes and reset only by a pointerdown inside the editor or a drag; a blur left it, and ProseMirror keeps its selection across a blur. On a phone, tapping the page away from the editor closed the keyboard, the mobile controller unmounted, and the desktop controller mounted with the stale state and showed the desktop toolbar over a blurred editor (desktop never showed it because the desktop popover's outside-press dismiss resets the store, but that only runs while it is mounted). The extension now subscribes toonFocusChangewith the editor's UI included: focus leaving resets the state, focus returning re-evaluates it unless a press or drag is in progress. Known edge: with focus inside the toolbar (a menu open), scrolling the selection out of view hides the toolbar and the browser drops that focus, so the toolbar is gone until the next selection change. Reproduced and verified on a Fairphone 5 over adb with the DOM read over CDP;mobileToolbar.test.tsxpins it (red before).SideMenuextension). iOS Safari delivers a tap as a hover first, one mouse move to the tap point, and drops the click when that hover changes the page. The side menu's documentmousemovehandler looked up the block under the pointer for any target inside the editor's UI too, found none under the mobile toolbar and hid a shown side menu, so the block type select and its items needed two taps whenever the side menu was showing. A move whose target is BlockNote UI outside the editor content now leaves the state as it is; on desktop that means hovering the formatting toolbar no longer moves or hides the side menu. Event and mutation logs from the simulator located it;mobileToolbar.test.tsxpins it (red before).useVirtualKeyboardcounts its mounted publishers and the last one out removes the--bn-vv-*properties from<html>; left behind, they pinned abn-scroll-containerto the keyboard-open height after a client-side navigation.DESKTOP_EXCLUDE.Android, dragdrop, multicolumn and mobile suites green in Docker after the side menu change; android Enter and keyboard-handler suites green after the filter merge and the interception removal.
