Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The fix prevents real pointer clicks from reopening the menu, but an edge case where a pointer sequence ends without a trigger click may cause a later label click not to open the menu.

Good catch on the A cancelled pointer sequence (touch scrolling, or the browser taking over the gesture) fires Reset the flag on 174/174 tests, lint and typecheck clean. |
nuxt#6575 synthesizes a pointerdown when a click lands while the menu reads as closed, so that a label click opens it. The dismissable layer normally makes the trigger unclickable while the menu is open, but a pointer-events utility on the trigger or an ancestor lets the click through: the outside pointerdown has already closed the menu, so open is false when click fires and the synthesized event reopens it. Gate the synthesis on the absence of a real pointerdown instead, which is the difference the surrounding comment already describes. Label clicks still forward a click with no pointerdown, so they keep working.
A cancelled pointer sequence, such as touch scrolling or the browser taking over the gesture, fires pointerdown with no matching click. The flag tracking a real pointer press therefore outlived the interaction and made the next label click look like a real press, so the menu stopped opening.

Reset triggerSawPointerDown when a pointer sequence ends without a trigger click.
The handler records every pointerdown, but the flag is cleared only by pointercancel and click. A right-click or a pointer released outside the trigger can produce no trigger click, leaving the flag set. After the menu closes, the next <label for> click can skip the synthetic pointerdown. Add a regression test for this sequence.

Resolves #6752
❓ Type of change
📚 Description
USelectcloses and then immediately reopens when the trigger, or any ancestor, carries apointer-eventsutility. The reporter hit it with the documented map-overlay pattern (pointer-events-nonecontainer,pointer-events-autocontrol), and their video shows it across Chrome, Firefox and Edge.This is a regression from #6575, which added a synthesized
pointerdownso<label for>clicks open the menu:openturns out not to be a reliable stand-in for "this click came from a label". Normally the dismissable layer makes the trigger unclickable while the menu is open, so a click on it never lands and the branch is unreachable. Apointer-eventsutility removes that protection: the outsidepointerdowncloses the menu first, soopenis alreadyfalseby the timeclickfires, the branch runs, and the synthesizedpointerdownreopens what the user just closed.The distinction the code actually wants is the one its own comment describes: a
<label for>click forwards aclickwith no precedingpointerdown. So the trigger now records whether a realpointerdownreached it and only synthesizes one when none did. The flag is reset at the end of the handler rather than the start, because the synthesized event re-enters thepointerdownhandler.Label clicks are unaffected: they still arrive without a
pointerdown, so they still open the menu.📝 Checklist
Behaviour only, no public API change, so nothing to document.
Tests. Added
a real pointer click does not synthesize a second pointerdownnext to the existing label test from #6575, which stays as the regression guard for that path. It countspointerdownevents reaching the trigger across apointerdownthenclicksequence and asserts exactly one.I first wrote the test to assert
aria-expandedafter a click, and it failed: the dismissable-layer close that makes this bug visible does not happen in the test environment, so that assertion was measuring the wrong thing. Counting the synthesized event tests the actual mechanism and is deterministic.Mutation tested: reverting only
Select.vueand keeping the test givesexpected 2 to be 1in both the nuxt and vue environments, confirming the secondpointerdownis real and that the test catches it.pnpm run test172/172,pnpm run lintandpnpm run typecheckclean.
