Last option in the "Platform" filter dropdown is cut in half and the menu has no bottom padding, unlike the padding above the search field, in the Hub Projects table

Steps to reproduce:

1. Open Unity Hub 3.21 and select Projects in the sidebar
2. Click the Platform filter in the filter bar
3. Observe the bottom edge of the opened dropdown, and compare it with the space above the "Search" field at the top of the same dropdown

Actual results: The third option is bisected by the bottom edge of the dropdown - only its top half is drawn - and there is no bottom padding, while the top of the same dropdown has clear padding above the search field. A user who does not attempt to scroll cannot tell that more platforms are listed below "Windows 64-bit"

Expected results: The dropdown sizes to whole option rows and leaves bottom padding consistent with the padding above the search field, so it is clear that the list continues

Reproducible with versions: Hub 3.21.0

Tested on (OS): MacBook Pro - Tahoe 26.6.1
