QColorDialog: Unable to pick color when using hover in stylesheet

When using a stylesheet that modifies hover, I'm unable to select a color because the color is changing when the mouse hovers over a color. When disabling the setStylesSheet call, setting the color applies when using the left mouse button and not when hovering. 

Not a fix, but just something I noticed: reverting the changes in https://github.com/qt/qtbase/commit/62f86b9b7ab3421c7a74c4c05a186847c76bfb28 (most specifically removing the line 'embeddedWidget(w)->setMouseTracking(true)' in src/widgets/styles/qstylesheetstyle.cpp) seems to address the issue as well. 

Issue does not happen on 5.13.1

#include <QApplication>
#include <QColorDialog>

int main(int argc, char **argv)
{
    QApplication app(argc, argv);
    app.setStyleSheet("QWidget:hover { color: #000000; }");

    QColorDialog::getColor();

    return app.exec();
}
