    Description

      If multiple undock widget is being tabbified and untabified it crashes.

      Adding this line in Qt's MainWindow example reproduces it:

        QMainWindow::setDockOptions((QMainWindow::DockOptions)(AllowNestedDocks|AllowTabbedDocks|GroupedDragging));
 

      Attached is the stack trace and screen recording and modified Qt's example.
