Selected Sample Stack remains showing in the Profiler when the frames are cleared and there is no data to select

Steps to reproduce:

1. Create a new Unity project using the Universal 3D template
2. Open the Profiler window (Window > Analysis > Profiler)
3. Enter Play Mode for some seconds for the Profiler to collect data
4. Exit Play Mode
5. Select the Hierarchy tab at the bottom of the Profiler window
6. Select any of the elements in the Hierarchy tab (PlayerLoop for example)
7. Press the "Clear" button to clear frames
8. Observe the Profiler window

Actual results: The selection remains, and there is a selection tooltip "Selected: PlayerLoop" while there is no data to select

Expected results: The selection is reset since there is no data in the Profiler
