mara, #3775: clicking a badge with its own dropdown open reopens it
instead of closing it. Root cause: the outside-click listener only
excludes the dropdown's own ref, not the sibling trigger that opened
it — a click on the trigger closes via that listener (pointerdown
fires first), then the trigger's own onClick toggle fires straight
after and reopens it, since its closure reads the pre-close state.
Dropdown now takes an optional anchorRef (the trigger's wrapper,
which callers already have for CSS positioning) and excludes it from
the outside-click check too — the same shape MetaNav's own hand-rolled
popover already uses correctly. Wired into StatusChips's Picker +
StatusMenu and swarm-ui's ComponentsPage demo (the only three Dropdown
consumers).
Verified two ways: reverted the fix, rebuilt, confirmed the bug
reproduces via a raw-CDP interaction test (two real clicks dispatched
through headless chromium, not just a static screenshot); restored
the fix, rebuilt, confirmed it passes.
