Allows focus to change when capture held

Allows focus to change when capture held

r186536 made it so focus focus changes while capture held are
ignored. Problem is we enter this scenario when activating a
window. In particular the window has capture, then we activate it but
the activation is ignored because it has capture. In this case we need
to allow the focus change else events are completely dropped.
