    Description

      Given a QMainWindow with two tabbed QDockWidgets, if you follow these steps, the app will crash unexpectedly:

      1. Launch the sample application. A main window with two docked group widgets will show.
      2. Undock one of the tabbed widgets by dragging the tab outside the main window to show a floating window with the tab contents.
      3. Undock the other tabbed widget from the main window and try to dock into the previously created floating window.
      4. Observe that the app crashes.

      Minimal reproducer app , Recording and stack trace attached.
