Comment 1 for bug 1030857

Instead of finding a good balance between radiance/ambiance themes, dark/light, I've set a transparent background to a couple of widgets that compose the hearder area.
The bug seems to be solved but .... we miss some separators to keep the whole content "organized".
As a side note switching to High contrast Inverse clear the test selection job names when I switch back to Ambiance. Another bug ?
