Frame Debugger Target Selection Search Results window becomes too tiny to even see the default “Editor” selection when there are no search results

Steps to reproduce:

1. Create a new Unity project using the Universal 3D template
2. Open the Frame Debugger window (Window > Analysis > Frame Debugger)
3. Open the Target Selection dropdown in the Frame Debugger window
4. Type something in the search bar that would have no results
5. Observe the Target Selection dropdown

Actual results: The Target Selection dropdown is too tiny to even see the default "Editor" selection

Expected results: The Target Selection dropdown has a minimum set size so that the default option "Editor" would be fully visible
