    Hi. I found UIToolkit bug related to ScrollView.

    When you touching scroll view after dragging scroll bar, its scroll position is unexpectedly changed.

    Reproduction step is super simple:
    1. Make scroll view.
    2. Add some labels until its scroll bar is shown.
    3. Play it on mobile device. (I tested on Android Galaxy S9+)
    4. Dragging scroll bar to bottom.
    5. Touch scroll view body.
    6. You can see that scroll position is reset to top.

    Tested on Unity 2022.2.0b4 + Android Galaxy S9+.

    Reported as IN-13558.

    This already happens in 2021.3.4f1 in my case, it’s not only related to this beta. A backport would be much appreciated.
