Build Analysis: Search field UI becomes hidden/obscured

Steps to reproduce:

1. Create or open the project
2. Window > Analysis > Build Analysis
3. Open "Assets" tab
4. Observe the Asset table interface: when the Build Analysis window is wide, the search field is visible
5. Resize the window to make it narrower, or dock it into a smaller panel layout 

Actual results: The search field completely vanishes from the UI view, preventing users from searching or filtering assets unless they manually expand the window to a massive horizontal size

Expected results: The search field should remain visible all the time

Reproducible with versions: 6000.6.0a6

Can’t test with versions: 6000.6.0a5 has no needed new functionality

Tested on (OS): Tahoe 26.4.1
