Although PlaceholderTransaction will use the selection on Merge, it is too late to use UpdateRange. Because RangeUpdater will be used after DoTransaction is finished. So we should update selection on DoTransaction. Also, part 1 fix doesn't update selection correctly via RangeUpdater when IME composition is multiple node.
