epriestley 3021e1d52d Allow only one global top menu to be open at a time
Summary: Fixes T3715. Makes "visible" global instead of per-menu, so all the menus share a visible state.

Test Plan: For menus A and B, clicked "A, A", "A, B, A", "A, B, B", "A, B, B, A", etc. Couldn't figure out a way to break it.
