    Description

      A main window with QMainWindow::GroupedDragging has two dock widgets: Dock A and Dock B. If you do the following sequence, Dock B cannot be moved anymore:

      1. make Dock A floating
      2. add Dock B as a tab of Dock A (by dragging)
      3. remove Dock B from Dock A
      4. Dock B is no longer movable
      5. close Dock B, reopen it
      6. Dock B is now movable but cannot be added to Dock A as a tab

      This can be reproduced with Qt Dock Widgets Example (examples/widgets/mainwindows/mainwindow). Just add dock option QMainWindow::GroupedDragging and follow the steps above.
