    Description

      1. Compile an run the attached sample (it opens main window with 2 tabbed QDockWidgetss)
      2. Dragging or using RMB undock both QDockWidgets and make them floating
      3. Dragging one of the windows dock them together in floating window
      4. Again undock both of them with RMB
      5. Move the windows again and see stray window appear
      6. Try docking them again -> CRASH (or assert in debug)
