      Description

      There is a very strange behavior with QDockWidget in my application after updating from Qt 5.6.2 to Qt 5.9.6.

      Reproduction:
      1. Start the attached program (code is based on qt "dockwidgets" example)
      2. Select View / Save state
      3. Close the customers and the paragraph window (menu View) -> Screenshot1_ok.png, all ok
      4. Select View / Restore state -> windows re-appear, all ok
      5. Close the customers and the paragraph window (menu View) -> Screenshot2_failure.png, failure

      With Qt 5.6.2, all is right ...
