      Description

      A maximized widget with Qt::Window flag is not correctly restored when parent window is minimized and restored back.

      Repro code:

      #include <QApplication>
      #include <QWidget>
      
      int main(int argc, char *argv[])
      {
          QApplication a(argc, argv);
      
          QWidget parent;
          QWidget child(&parent, Qt::Window);
      
          parent.setWindowTitle("Parent");
          child.setWindowTitle("Child");
      
          parent.showMaximized();
          child.showMaximized();
      
          parent.setWindowState(Qt::WindowMinimized);
          parent.setWindowState(Qt::WindowMaximized);
      
          return a.exec();
      }
      

      The child should be restored to maximized state but is instead restored to normal state.
