      1) Run attached sample.
      2) Click "CreateSubWindowOnWidget”to create child window.
      3) Click "CreateSubMainWindow”to create grandchild window.
      4) Move grandchild window and click window close button on child window (created by step 2)

      FYI:

      • It can not reproduce if QMainWindow subclass don't have embedded QQuickView.
      • It can not reproduce if QQuickWindow is not on QMainwindow but QDialog. (you can confirm this enable comment on widget.cpp)
