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