[REG 6.3.2 -> 6.4] Native QOpenGLWidget in QMainWindow breaks menu bar

Code

#include <QApplication>
#include <QMainWindow>
#include <QOpenGLWidget>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    app.setAttribute(Qt::AA_NativeWindows);

    QMainWindow w;
    w.setCentralWidget(new QOpenGLWidget);
    w.menuBar()->addAction("Hello");
    w.show();

    return app.exec();
}

Outcomes
The menu bar text does not appear. The debug output shows the following messages at startup, as well as every time you move your mouse cursor over the menu bar where the text is meant to be:

QOpenGLContext::makeCurrent() called with non-opengl surface 0x19699b03180
QRhiGles2: Failed to make context current. Expect bad things to happen.

Notes

• The problem doesn't occur if QMenuBar::addAction() is not called
• The problem doesn't occur if Qt::AA_NativeWindows is removed
