When a horizontal filter bar has enough native filters to overflow into the "More filters" dropdown, applying a cross-filter (which prepends a chip to the bar's item list) could make the overflowed native filters vanish from BOTH the bar and the dropdown, while the "More filters" button itself also disappeared, leaving the hidden filters unreachable. Clearing the cross-filter restored them. Root cause: when the item set changes, DropdownContainer resets its positional overflow index and re-measures. If that measurement runs against a transient mid-reflow layout, it can conclude "nothing overflows" and latch that verdict (the recalculation effect's dependencies do not change again, so it never self-corrects). Because the trigger's visibility is derived solely from the overflow count, that single bad verdict both strands the surplus filters in the clipped bar and removes the trigger to reach them. Fix: treat a post-item-change "nothing overflows" read as provisional and run a single requestAnimationFrame confirmation pass that re-measures once the browser has reflowed, keeping the trigger mounted across the confirmation window. The confirmation is armed on every item-set change (so a fit->overflow transition is covered, not only the already-overflowing case) and is versioned and cancelled so a superseded frame from a rapid second change cannot clobber the newer state. This extends the intent of #38193 (which guarded only the transient reset window) to also cover a settled bad read, and is in the same overflow/button visibility area as #28060. Adds DropdownContainer.overflow.test.tsx, which drives the real overflow recalculation (mocking only the two measurement sources) and covers: a clean re-measurement after a prepended chip, the transient-latch regression, the fit->overflow transition, over-correction (genuine fit drops the trigger), and re-entrant item-set changes.
