The OnPointerEventObserved() interface acts differently between mash and
mus/classic. In mus/classic, the target window is taken from the
LocatedEvent's target(), relying on previous event dispatch metadata. On
mash, this event came from a remote service which hasn't been targeted,
target is therefore the top of the window tree. In the --mash case only,
target the event on the window and use that as the window we pass to the
rest of the system.
