The frontend caches statuses and only asks about unknown keys, so flipping
the chase mode left half the screen judged under the old rules until a
restart — which read as the mode not working. The backend now broadcasts an
invalidation and the panels re-ask as rows repaint. The entity badges also
say their name with a question mark, dashed, when the need is only a missing
QSL — the 50% opacity was invisible on a filled chip.
