Steps to reproduce:

1. Open Unity Hub
2. Install  6000.3.5f1 or 6000.3.4f1 or 6000.3.4f1 
3. Open the "Projects" window
4. Click the "New Project" button
5. Scroll to the installed build
6. Hover the mouse above the "Warning" section
7. Verify that you get a tooltip
8. Scroll the list and observe the tooltip behaviour

Actual results: When scrolling in the Project window, the tooltip remains visible and overlaps other UI elements, obscuring content and interfering with the layout

Expected results: The tooltip does not overlap other elements while scrolling in the Project window.

Reproducible with versions: 3.16.3
