Subject: [PATCH] Align History regressions with wrapped tooltips and empty
 announcements

Retain exact geometry controls for the taller tooltip and assert empty announcement text rather than absence of Solid's empty text node.

Contract-Neutral: Test-only expectations for the existing keyboard inspection and tooltip repair; no runtime or interface change.
