[Reg 6.2 -> 6.5+] Minimizing + Restoring QMainWindow should not restore a hidden QDockWidget

Code

#include <QtWidgets>

int main(int argc, char* argv[])
{
    QApplication app(argc, argv);

    QMainWindow mw;
    mw.addDockWidget(Qt::LeftDockWidgetArea, new QDockWidget);
    mw.setCentralWidget(new QWidget);
    mw.show();

    return app.exec();
}

Steps to reproduce

1. Build and run the code above
2. Close/hide the dock widget by clicking its 'X' button
3. Minimize the top-level window
4. Restore the top-level window

Expected outcomes (Qt 6.2.11, 6.6.1)
The dock widget remains hidden

Actual outcomes (Qt 6.5.4, 6.7.0b2)
The dock widget is restored
