We must call UpdateTextInputState every time after |handling_ime_event_| flip
from true to false, right?

If so, please add comment.

This bool is just used to make sure that we don't send UpdateInputState during
the handing_ime_event. For example confirmComposition has an in-between stage
where the word in composition is deleted and then a final state when it gets
added fully (all this happens in Editor.cpp).
