Longer Add Component submenu labels obscure UI and are not truncated

Steps to reproduce:

1. Create or open an HDRP setup Project
2. Select any GameObject in the Hierarchy of a Scene
3. In the Inspector scroll to the bottom and click on "Add Component"
4. Select "Scripts" in the submenu
5. Select one of the longer string entries (e.g. "UnityEngine.Rendering.HighDefinition...")
6. Observe the top of the submenu

Actual results: Submenu labels that are longer obscure the "Go back arrow" and are not truncated

Expected results: The "Go back arrow" is not obscured by the label and the submenu name is truncated
