Upon further thought, I think we should also fire a textInput event here
(not sure if it should fire before or after compositionstart). "data" can
just be the empty string. It should be possible to only listen to textInput
and preventDefault to prevent all text insertion. You shouldn't need to
listen to both textInput and keydown/compositionstart.
