Given a QMainWindow with two tabbed QDockWidgets, if you follow these steps, the app will crash unexpectedly:
- Launch the sample application. A main window with two docked group widgets will show.
- Undock one of the tabbed widgets by dragging the tab outside the main window to show a floating window with the tab contents.
- Undock the other tabbed widget from the main window and try to dock into the previously created floating window.
- Observe that the app crashes.
