I had a similar problem and it seems that even with Priority = Application
the default theme is overriding "override_background_color()". I would
like to know if this is a bug as I wasted several hours trying to find the
work around and ended up having to use the css method with the applicable
config from the default theme which seems a little excessive when a 1
liner in code should be possible.
