first rebase

ALSO: Remove fading on dropdown menu click. This is also a bug on the actual upstream, when the cursor leaves the screen the menu disappears but the fading doesn't.
This causes things like the menu saying it's open when it's not and closed when open. I'm not dealing with an upstream bug.
