The first background in the priority order is always the one you've selected by default (through downloading metadata)
I'm not sure if this is a bug on my end but in order to use animated backgrounds I had to turn on automatic or random change for backgrounds, I couldn't just use an animated background first in the order.
The ability to change which background is used through the extension without enabling automatic change would be a nice feature.
