See upcoming testcase.
I expect a green background color, but it is red in Mozilla.
This also happens in Mozilla1.7.

This is "by-design" as far as I can tell.  The idea is that the XBL-provided rules are at the level between preshints and document rules.  It's been that way since 2000 or so, as far as I can tell.  In fact ever since the fix for bug 21890 introduced the current way of XBL styling.

Ok, feel free to wontfix it.
But this doesn't seem logical to me.

It's logical because the XBL stylesheets provide default styling for the widget.  If the XBL then doesn't want the widget to be styled further by the document, it can say so, of course.
