How to un-focus element when removing from hierarchy?

Hi. I implemented in-game window system by using UI Toolkit.

To close window, I removed the root element of the window from hierarchy (RemoveFromHierarchy() method). But after removing, it is still focused and InputSystemUIInputModule still access to it.

How to un-focus VisualElement for preventing input-interaction?

Thanks.

Found that Blur() method makes it.

Glad you found a workaround. This sure sound like a bug that should not have occurred in the first place.

This problem still exist (or again).
I reuse my elems and they didn`t unfocus automatically when were removed from parent.
Solution also invoke ele.Blur() after event DetachFromPanelEvent;
