A friendly reminder that M59 Beta  launch is coming soon! Your bug is labelled as Release Block Beta. All fixes need to be merged into the release branch (3071) latest by tomorrow, 04/26 4:00 PM PT in order to make into the desktop Beta final build cut. Thank you!

msw: Can I give you this to resolve or reassign? Thanks. :)

ThemedSolidBackground -> estade

Won't block Beta for this, pushing to ReleaseBlock-Stable.

I do not understand how this could be present in M59. Why do we believe it's in 59? It landed well after the branch point and it has been reverted (the fix is simple and I will re-land soon).
