	This fixes various things, like sort arrows not working, even in regular non-mixed-color-scheme settings, and is a lot less code. The toolbarbutton appearance on the problematic case described in comment 0 could get some work (the extra borders aren't exactly pretty), but it's still a much better improvement.
