* fix autofill events * ignore the wrong type of event like we do in desktop * check the event type before dispatch instead of panicing on downcast * clean up conversion * remove example * pull out shared event list * pull in deserialize_raw * unified event list * prettier comment * restore test * restore alias * normal doc comments * move over comments * minimize diff * remove alias, was moved into the macro
