📝 WalkthroughWalkthroughMenu and popover global handlers now follow connection lifecycle callbacks and connection-state guards. Trigger ARIA attributes remain explicit when closed. Menu disabled handling preserves consumer-set disabled attributes. End-to-end tests cover these behaviors. ChangesPopover and trigger updates
Priority: ⬇️ Low Estimated code review effort: 3 (Moderate) | ~20 minutes Change: Bug fix Merge Risk: 🔵 Low · up to This change improves popover and menu listener lifecycle handling and preserves consumer-set disabled attributes on menu triggers, without introducing new defects in the reviewed logic. One test case should be strengthened to actually toggle the menu's disabled state while a consumer-owned disabled attribute is present, ensuring the intended protection is verified end-to-end; this is a low-risk follow-up rather than a merge blocker. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

`removeEventListener` only matches a listener registered with the same capture flag. The click listener was added with `capture: true` and removed without it, so it stayed on `document` for the life of the page. Nothing misbehaved while the popover was alive, because the handler checks `open` before acting, but the listener held on to a detached popover and everything it referenced. The popover also had no `disconnectedCallback`, so one removed while open went on listening. Setup now runs on connect and teardown on disconnect, which also restores the listeners if the element is moved in the DOM. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`aria-expanded` was removed from the trigger whenever the popover was closed, so it read as an ordinary button: nothing announced that there was something to open, and closing it announced nothing at all. It is now written in both states, which is what the attribute is for. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

It is now written in both states, as `limel-popover` already does, so a consumer supplying a trigger to either gets the same DOM back. `disabled` keeps the remove-when-false path, because there the presence of the attribute is what disables the element.

Test consumer-owned disabled state across the menu toggle. The consumer-owned trigger is reachable through the menu’s trigger slot. setTriggerDisabled tracks only attributes added by the menu, so a consumer-owned attribute must remain after setProps({ disabled: false }). The existing toggle test covers only a menu-added attribute, while the consumer-owned test performs no toggle. Add the toggle and assert that the trigger still has disabled.

`setTriggerAttributes` cleared `disabled` from the slotted trigger on every render whenever the menu itself was enabled, no matter who had put the attribute there. A consumer writing `<limel-button disabled slot="trigger">` inside an enabled menu had it stripped, and because that prop reflects, their button was silently re-enabled. The menu now tracks the triggers it disabled itself, and only clears the attribute on those. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`openWatcher` added the capturing `keydown` listener whenever `open` turned true, without checking that the host was still in the page. Stencil keeps firing `@Watch` on a detached instance, so a consumer setting `open = true` on a menu they had already removed put the listener back with no `disconnectedCallback` left to take it down. That kept the instance alive, and a hotkey press then ran selection on a component that is no longer in the page. Setup and teardown now go through one matched pair, the shape `limel-popover` already uses, instead of three inline copies of the add and remove.

Two defects in how
limel-popovertreats the trigger element it is handed, and the same accessibility fix inlimel-menu, which carries a copy of the same code. No new behaviour; nothing here is specific to the component that turned them up.The document click listener was never removed
The listener is added with
{ capture: true }and was removed without it.removeEventListeneronly matches a listener registered with the same capture flag, so the removal never matched and the listener stayed ondocumentfor the life of the page.Nothing misbehaved, because the handler checks
openbefore acting — but every popover that had ever been opened kept a capturingdocumentlistener, and that listener holds its host, so a popover removed from the page could not be collected.The popover also had no
disconnectedCallback, so one removed while still open went on listening. Setup now runs on connect and teardown on disconnect, and both use the same capture flag.aria-expandeddisappeared instead of sayingfalsesetTriggerAttributeswrote the attribute when open and removed it when closed. A closed trigger therefore read as an ordinary button: nothing announced that there was anything to open, and closing it announced nothing at all. It is now written in both states, which is what the attribute is for.Why
limel-menuis in here toolimel-menuhas its own copy of the same four lines. Fixing only the popover would have left the two writing different DOM onto a consumer-supplied trigger — a closed popover trigger readingaria-expanded="false"while a closed menu trigger had no attribute at all — so a consumer with one selector or one test covering both would have had to handle two shapes. The menu keeps the remove-when-false path fordisabled, because there the presence of the attribute is what disables the element.What changes for consumers
The one visible change is that closed triggers now carry
aria-expanded="false"where they previously carried nothing. I checked everyaria-expandedselector in lime-elements, lime-crm-components and lime-crm-building-blocks: they are all either[aria-expanded='true'],[aria-expanded]:not([aria-expanded='false']), or a:not([aria-expanded='true'])negation. None of them matches a bare[aria-expanded], so nothing restyles.Testing
The full suite passes (2457 tests). These three commits add no tests of their own, so the two behaviours are not pinned: I can add a
popover.e2e.tsxasserting that a closed trigger readsaria-expanded="false"and that removing an open popover leaves no capturing listener ondocument, if you would rather have that before this merges.🤖 Generated with Claude Code
