The overflow menu's trigger selector matched its own popover's menu
items too (they sit inside the same wrapper), so a click resolved to
5 elements instead of 1 — scoped to [data-md-menu-trigger]. Escape's
close is the browser's own light dismiss (menu.js), so a click right
after it needs to be past the 250ms reopen guard, as the same pattern
already is elsewhere (ActionsTest.php); the reopen test now waits.
Also adds the reviewer's requested coverage: the section nav's list
items share the row's width equally regardless of label length, and a
plain wire:model tab switches its panel locally without reaching the
server per click while wire:model.live does, one request that also
flushes the deferred property along with it (plan step 36).
