On Mac, menu actions no longer trigger after calling menu.clear() and repopulating inside of a slot triggered by the menu aboutToShow() signal

void TestQtAPI::slotAboutToShowMenu() {
	if (menu != NULL) {
		menu->clear();
		menu->addAction("Dummy", &loop, SLOT(quit()));
	}
}

void TestQtAPI::testSubmenuWorksWithoutWindows() {
	QMenuBar mb;
	menu = mb.addMenu("Dummy");
	menu->addAction("Dummy", &loop, SLOT(quit()));
	connect(menu, SIGNAL(aboutToShow()), this, SLOT(slotAboutToShowMenu()));
	
	QPoint inside1(150, 10);
    QPoint inside2 = inside1 + QPoint(0, 30);
	
	// Post a click to press the menu item:
	NativeEventList native;
    native.append(new QNativeMouseButtonEvent(inside1, Qt::LeftButton, 1, Qt::NoModifier));
    native.append(new QNativeMouseButtonEvent(inside1, Qt::LeftButton, 0, Qt::NoModifier));
    native.append(new QNativeMouseButtonEvent(inside2, Qt::LeftButton, 1, Qt::NoModifier));
	native.append(new QNativeMouseButtonEvent(inside2, Qt::LeftButton, 0, Qt::NoModifier));

    // Add a backup timer to end the test if we fail:
    QTimer dontHang;
    dontHang.setSingleShot(true);
    connect(&dontHang, SIGNAL(timeout()), &loop, SLOT(quit()));
    dontHang.start(3000);

    native.play(NativeEventList::ReturnImmediately);
    loop.exec();
    QVERIFY2(dontHang.isActive(), "The item was not triggered!");
}
