Currently opening editor triggers a menu open sample, coming from EditorMenuBar which inherits from OsuMenu. Seems like that should not play any sounds on AnimateOpen/AnimateClose.

I've fixed the above with a local guard checking that the menu is not a TopLevelMenu.

Possibly arguable that those menus shouldn't have Animate{Open,Close} called on them in the first place, but that'd be a framework amendment, so not sure whether that's something for now or later. Depends on how much this is desired to be in the next release or not, I suppose.

Hard one to decide, one may want to perform transforms when showing a menu bar (I can envision that potentially happening with editor at some point).

Not playing on TopLevelMenu sounds logically sufficient.
