* Work around a bug that was present before Jelly Bean upon rotation.
*
* Before Jelly Bean, there is a bug where setComposingRegion and other committing
* functions on the input connection get ignored until the cursor moves. This method works
* around the bug by wiggling the cursor first, which reactivates the connection and has
* the subsequent methods work, then restoring it to its original position.
*
* On platforms on which this method is not present, this is a no-op.
