Reviewed by Antonio Gomes.

The selection handler deliberately drops caret change notifications
while the input handler is processing changes, to avoid displaying
intermediate state during a complex change.

However, this meant that the client was never informed of the final
caret position.

Fixed by notifying client about caret change after processing ends, if
one or more caret change notifications were dropped during processing.
