 100     Test removes the transition properties while the transition is running, then adds them back in.
 101     If working properly the transitions should start from the beginning. But there was a bug that
 102     would cause the transition to continue to run (although with no visible effect). So when you
 103     restarted, it would pick up where it left off.
