Desktop windows : When the window is resize (ex : height is changed) -> thumb position is not correct

Hi,

When the window is resize (ex : height is changed) -> thumb position is not correct.

Steps :
- Window is fullscreen, scroll position top most
- Scroll down to middle
- Resize window to smaller height
- Scroll to top

Thumb will not reach top position

Maybe must add layout builder ? Not sure

Edit : already using layout builder, dont know why still not updating the scroll position

Edit : Using scroll wheel to scroll up
