Hierarchy V2 search filter chips are cut off and not properly truncated

Steps to reproduce:

1. Create a new project
2. Ensure that "Use New Hierarchy Window" is enabled in Unity > Settings > General >Use new Hierarchy window
3. Click on the Hierarchy search icon and add any search filter (for example: Components > Adaptive Performance Manager)
4.  Add one more search filter (for example: Layers > Water)
5. Resize the "Hierarchy" window. Make it narrower
6. Observe the search area

Actual results: Search filters in the Hierarchy Query Builder are cut off. Search filter separators in the Hierarchy Query Builder are misaligned.

Expected results: Search filter chips, separators, and controls are fully visible and properly aligned. If text exceeds available space, it is truncated with “...”.
