When using UI Toolkit for in-game UI and previewing in the game view, the element under mouse gets reset every time another element moves.

Steps to reproduce:
1) In a project / Unity versions which has runtime capability, import the attached Unity package
2) Open the scene
3) Enter playmode
4) Try to hover the button and observe the hover color of the buttons is absent or flickers
5) Exit play mode, disable the "Simple Panel" script (it causes a red square element to animate)
6) Observe the hover state of buttons is correct

Expected: hover state is correct even if another element is animating
