[Frame Debugger] Frame event data doesn't update after clicking on frame navigation arrows and not moving the mouse



Reproduction steps:
1. Open user's project ""
2. In the top toolbar select File/Build Settings...
3. Make sure Development Build is selected
4. Press on Build and Run, wait for it to build
5. In the built solution window press Alt-Enter to enter windowed mode
6. Go to Unity Editor, open Frame Debugger in top toolbar/Window/Analysis
7. In the Frame Debugger window, click on the dropdown menu and select the process of built solution (Probably called WindowsPlayer(Machine Name))
8. Click Enable and move your cursor to the arrow pointing left, in the right top corner of the Frame Debugger window
9. (Important) Don't move your mouse and then try left-clicking on the arrow (You need to click without moving the mouse at all)
10. Wait for 10 seconds or more, and then move your mouse

Expected result: Frame debugger loads frame event data right away after clicking on frame navigation arrows
Actual result: Frame debugger is stuck on "Receiving frame event data..." when you don't move your cursor after clicking on frame navigation arrows and will not change until you move your mouse

Reproducible with: 2018.4.34f1, 2019.4.31f1 2020.3.21f1, 2021.1.25f1, 2021.2.0b16, 2022.1.0a5
Not reproducible with: 2022.1.0a6, 2022.1.0a12

Note: It might take a few mouse clicks to reproduce because mouses with good sensitivity will detect movement upon clicking
