QScrollArea misbehaving background style

[Cruz]

Hi there.

I'm trying to style a QScrollArea with an external style sheet and it doesn't work right.

QScrollArea, QAbstractScrollArea, QWidget[isScrollArea="true"] {
	background-color: black;
	background: black;
}

QScrollArea, QAbstractScrollArea, QWidget[isScrollArea="true"] {
	background-color: black;
	background: black;
}

To copy to clipboard, switch view to plain text mode 

With this style I can only influence a thin border of the scroll area. The background color of the main part only reacts to this:

QWidget  {
	background-color: black;
	background: black;
}

QWidget  {
	background-color: black;
	background: black;
}

To copy to clipboard, switch view to plain text mode 

As you can see I also tried using QAbstractScrollArea and even a QWidget style reacting to the dynamic property "isScrollArea". Is anyone else having the same problem?
