How to combine stylesheet descendant selector with property selector?

[Jakob]

I had expected the following would work:

*[styleAsPresetPanel="true"] QPushButton,
*[styleAsPresetPanel="true"] QCheckBox
{
   /* stylesheet */
}

This would mean that stylesheet would need to apply to any QPushButton or QCheckBox that is a descendant of any object that has the dynamic property styleAsPresetPanel set to true.

Am I trying to do something that is simply not possible, or do I need to change the syntax?

I just noted that without the '*' it does work, in other words, the following works:

QFrame[styleAsPresetPanel="true"] QPushButton,
QFrame[styleAsPresetPanel="true"] QCheckBox
{
    /* stylesheet */
}

Allthough this is enough for me to continue for now, my original question remains. I'd expect this to work with the '*' as well, but that doesn't seem to work. Is that a bug I should file, or are my expectations wrong?
