Resizing the tabs in UI Toolkit Debugger briefly highlights the UI Element when the mouse is hovering over the Element and moves fast
How to reproduce:
1. Create a new Unity project
2. Create a new UI Document and open it
3. Open the three-dot menu of the UI Builder window and open the UI Toolkit Debugger
4. Click and drag the tab separator to resize the Layout and Styles tabs
5. Move the mouse quickly while hovering on the "EditorPanelRootElement"
6. Observe the results
Expected results: No highlighting of the UI element occurs
Actual results: When moving the mouse fast a brief highlighting of the UI Element occurs resulting in the flickering
Reproducible with: 2021.3.40f1, 2022.3.39f1, 6000.0.13f1
Reproducible on: macOS Sonoma 14.5 (M1)
Notes: In 6000.0.13f1 the mouse cursor is not changed to the arrows when resizing but hovered on the UI Element. However, in 2021.3.40f1, it can be observed that during the fast resizing, the mouse quickly changes from the arrow to a standard cursor, resulting in selecting the UI Element and highlighting.

Resolution Note:
Thanks for the report. This happens because some events still get sent to other elements even when hovering. While in this particular case, it would have been better to not trigger the treeview item hover that highlights the UIB window, the fix would be far more risky and complicated than the symptom. It's not something we can tackle at this time.
