Reproduction steps:
1. Open the attached "Repro" project
2. Open the "Assets/Scenes/SampleScene" scene
3. Enter the Play Mode
4. Try to scroll with the mouse wheel or click on the slider arrows
5. Observe the results
Expected results: The slider moves when scrolling or clicking the slider arrows
Actual results: The slider does not move when scrolling or clicking the slider arrows
Reproducible on: Windows 11 Pro
Not reproducible on: No other environments tested

Scrolling and arrow buttons start to work after clicking and dragging the slider
Scrolling while it's entering the Play Mode sometimes unstucks the slider and makes it possible to scroll on the affected versions without having to click and drag the slider
