If you have a TreeView with LoadChildrenOnDemand enanled and CheckBoxMode set to "Recursive", when the user checks an unexpanded item ( which children are not loaded yet), the expand icon disappears and the user is not able to expand the item.

Imagine large list of expanded and collapsed items which completely does not fit on the screen in RadTreeView. User scrolls to the middle of the list. User doesn't select anything from the list, just looks. User closes the application, and the application saves TreeView's current scroll positions in some file. Next user opens the application. After items are loaded I want to scroll RadTreeView in code to the position from the previously saved data in file.

If we have a TreeView control inside a Popup, and the TreeView is operated with a finger, everything works perfectly.
However, if there is interaction with the treeview items with a stylus (Samsung Galaxy Tab S6), the app crashes regularly.
