Bug Automatic Scroll

There is an unwanted behaviour happening for the UI in the new versions of the unity editors.

For example the slider in this screenshot can't be used. You can change its position by clicking somewhere on the slider, but as soon as you try to drag it the UI scrolls to the top. The same thing happens when you drag on any UI element, like text fields or buttons. This behaviour didn't happen in the 2021.3.4f version. It appeared in the versions afterwards.
The UI was made using the UI Toolkit.

 

If I had to guess it might be a bug in the UI Toolkit related to auto-scrolling to the last selected element.

Perhaps try changing the focus to another item, or to no item. I know on the old UnityEngine.UI system you set the selected GameObject in the EventSystem.

With UIToolkit I am not sure. My cursory reading of UI Toolkit docs seems to indicate perhaps that system isn't really finished yet or ready for prime time. I direct you to this line:

"Note: Unity recommends you to use UI Toolkit for your new UI development projects. However, Unity UI (uGUI) and IMGUI are appropriate for certain use cases, and are required to support deprecated projects. For more information, see the Comparison of UI systems in Unity."

as written in this page:

You probably should be posting this in the correct subforum: https://forum.unity.com/forums/ui-toolkit.178/

I would be surprised if this can't be customised. I would look through the API documentation to see if there's any appropriate properties for this.
