QStyle::name() is empty when using stylesheets

I'm trying to determine the current style name but I get an empty string when I use qApp->setStylesheet(). I suggest the "stylesheet style" should return the name of the proxied style.

qDebug() << QApplication::style().name();

I also tried casting to QProxyStyle and getting the baseStyle but it returns QApplication::style() as documented, i.e. always the "stylesheet style".

 auto style = qobject_cast<QProxyStyle *>(QApplication::style())->baseStyle();
