📚 Description

USelect closes and then immediately reopens when the trigger, or any ancestor, carries a pointer-events utility. The reporter hit it with the documented map-overlay pattern (pointer-events-none container, pointer-events-auto control), and their video shows it across Chrome, Firefox and Edge.

This is a regression from #6575, which added a synthesized pointerdown so <label for> clicks open the menu:

if (!open) {
  triggerRef.value?.$el?.dispatchEvent(new PointerEvent('pointerdown', { bubbles: true, button: 0 }))
}

open turns 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. A pointer-events utility removes that protection: the outside pointerdown closes the menu first, so open is already false by the time click fires, the branch runs, and the synthesized pointerdown reopens what the user just closed.

The distinction the code actually wants is the one its own comment describes: a <label for> click forwards a click with no preceding pointerdown. So the trigger now records whether a real pointerdown reached 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 the pointerdown handler.

Label clicks are unaffected: they still arrive without a pointerdown, so they still open the menu.

📝 Checklist

• I have linked an issue or discussion.
• I have updated the documentation accordingly.

Behaviour only, no public API change, so nothing to document.

Tests. Added a real pointer click does not synthesize a second pointerdown next to the existing label test from #6575, which stays as the regression guard for that path. It counts pointerdown events reaching the trigger across a pointerdown then click sequence and asserts exactly one.

I first wrote the test to assert aria-expanded after 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.vue and keeping the test gives expected 2 to be 1 in both the nuxt and vue environments, confirming the second pointerdown is real and that the test catches it.

pnpm run test 172/172, pnpm run lint and pnpm run typecheck clean.

📝 Walkthrough

Walkthrough

Select.vue now tracks real pointer presses on the trigger and clears the state on pointercancel. When the menu is closed and no real pointer press occurred, onTriggerClick dispatches a synthetic pointerdown. Tests cover genuine pointer clicks and cancelled pointer sequences.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to b2c7f

This change prevents real pointer clicks from reopening the Select menu while preserving label-triggered opening. No actionable merge-blocking risk remains after normal checks and review.

_{Comparing rajanpanth:fix/select-pointer-events-reopen (b2c7f68) with v4 (ae24311)}

[rajanpanth]

Good catch on the pointercancel case, that was a real gap and I've pushed a fix.

A cancelled pointer sequence (touch scrolling, or the browser taking over the gesture) fires pointerdown with no matching click, so triggerSawPointerDown stayed true past the end of the interaction. The next <label for> click would then look like a real pointer press and the menu would not open, which is exactly the case #6575 exists to handle.

Reset the flag on pointercancel, and added a test covering pointerdown, pointercancel, then a label-style click. Reverting only the new handler while keeping that test gives expected 1 to be 2 in both the nuxt and vue environments, so it does catch the regression.

174/174 tests, lint and typecheck clean.
