OS X: QWindow::setGeometry() and QWindow::resize doesn't emit signals for windows embedded in native windows

void QWindow::setGeometry(const QRect &rect)
{
    Q_D(QWindow);
    d->positionAutomatic = false;
    if (rect == geometry())
        return;
    QRect oldRect = geometry();

    d->positionPolicy = QWindowPrivate::WindowFrameExclusive;
    if (d->platformWindow) {
        d->platformWindow->setGeometry(rect);
    } else {
        d->geometry = rect;

        if (rect.x() != oldRect.x())
            emit xChanged(rect.x());
        if (rect.y() != oldRect.y())
            emit yChanged(rect.y());
        if (rect.width() != oldRect.width())
            emit widthChanged(rect.width());
        if (rect.height() != oldRect.height())
            emit heightChanged(rect.height());
    }
}

void QWindow::resize(const QSize &newSize)
{
    Q_D(QWindow);
    if (d->platformWindow) {
        d->platformWindow->setGeometry(QRect(position(), newSize));
    } else {
        const QSize oldSize = d->geometry.size();
        d->geometry.setSize(newSize);
        if (newSize.width() != oldSize.width())
