Same root cause as #356 -- the textarea (when not doing comoposition) is positioned in the top left corner of the editor. When we get a compositionstart event, we move the textarea near the primary cursor. In this case, I think we don't get any event until an emoji is picked and we don't get a chance to reposition the textarea.
