Comment 39 for bug 1599453

I was just thinking about the background, and realized it's because the last css bit is in an if clause (if self.config['handle_size'] etc) and it overwrites the previous css string. However, it then adds the css as a new provider outside the if clause. If you didn't enter the if clause, it will be the same as before, but since this is happening after the terminator.css and terminator_styling.css files are imported, that css will take precendence.

So, that diff I sent should fix it, because it changes the if clause to append to the css, and then only sets the provider once, before any of the css files that will override it.
