QColorDialog: WA_Hover breaks color and luminance picker

It's a side effect of this patch:
https://codereview.qt-project.org/c/qt/qtbase/+/318526
that solves this bug:
https://bugreports.qt.io/browse/QTBUG-87706

QColorDialog behavior is broken if its stylesheet contains 'hover' (even if it's a completely dummy sheet without doing anything). When mouse is hovering above color panel, color changes when mouse moves even without clicking. A minimal reproducer:

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

    QColorDialog* cDiag = new QColorDialog;
    QString* str = new QString("QWidget:item:hover"
                                "{"
                                "}");
    cDiag->setStyleSheet(*str);
    cDiag->show();

    return app.exec();
}

So if the patch solves QPushButton issue, then probably it is better to limit the scope to QPushButton only. A possible patch is uploaded. What is the possibility of it being merged into further release and/or backporting to old versions?
