not blocking on this since it's a limited use-case (browsing background themes with downloads panel open), though the number of toolbar bugs caused by browsing background themes is impressive, pretty clear there's an architectural problem there.

Since this issue is no longer relevant in the current Firefox versions, I'm closing it.
