The RadTreeViewItem preserves its state when it is disabled
When the RadTreeViewItem (or the RadTreeView) is disabled and after a delay is enabled again it should go in "Normal" state. Now the control preserves its state, hence you are able to send more than one RadTreeViewItem in "Hovered" state.

The bug seems to be caused by an incorrect value in IsMouseOverHeader of TreeViewItem, after the enable state has toggled.
