[UI Toolkit] Debugger window is very slow with specific elements
Reproduction steps:
1. Create a new Project
2. Open UI Toolkit Debugger (Ctrl + F5 on Windows 10 or via Inspector ellipsis menu)
3. Select GameView (Game View needs to be visible)
4. Expand Visual Element #unity-panel-containerX
5. Select Visual Element #rootVisualContainerY
6. On the right of the window move the mouse across the margin, border, padding
Expected result: the selected area instantly lights up when the cursor is above it (like with other elements)
Actual result: the selected area lights up with a delay, it feels like the editor is lagging
Reproducible with: 2020.3.32f1, 2021.2.18f1, 2022.1.0b14, 2022.2.0a9
Not reproducible with: 2019.4.37f1
Tested on Windows 10
Notes:
1. Resource monitoring software (Task Manager) indicates that CPU usage for the editor is less then usual if moving the cursor above the area in step 4 rapidly (with other elements there is no change in CPU usage)
