Summary:

  CloseWatcher is a new primitive that consolidates the various mechanisms for closing floating UI (dialogs, popovers, fullscreen) abstracting away from the input method (esc keypress, touch gesture etc), as well as allowing web developers to implement their own watchers of these gestures.

I intend to prototype this out in Gecko.
