This is a Mac only bug. If the user was in the middle of IM text composition
and clicked on a different node the partially composed text was left in the old
node and the IM window wasn't dismissed. This PR implements the existing
finishInputMethodComposition call so it can commit the text and dismiss the IM
window before focus moves away from the node where composition was taking place.
This PR changes the implementation of `unmarkText` to match what we want and
what Apple says it should do ("The text view should accept the marked text as
if it had been inserted normally"). With that said I haven't found an IME that
calls this routine.
