  // This test checks that a call to setCurrentTime flushes restarts
  //
  // Actually, this same scenario arises in test_smilRestart.xhtml but we
  // isolate this particular situation here for easier diagnosis if this ever
  // fails.
  //
  // At first we have:
  //                       currentTime   begin="100s"
  //                            v            v
  // Doc time: 0---\/\/\/-------99----------100-------
  //

  // Then we restart giving us:
  //
  //                       beginElement begin="100s"
  //                            v            v
  // Doc time: 0---\/\/\/-------99----------100-------
  //
  // So our current interval is
  //
  //                            begin="100s"
  //                                v
  //                            +---------------|
  // Doc time: 0---\/\/\/-------99-100-101-102-103-----
  //
  anim.beginElement();
  is(anim.getStartTime(), svg.getCurrentTime());

  // Then we skip to half-way, i.e.
  //
  //                                currentTime
  //                                    v
  //                            begin="100s"
  //                                v
  //                            +---------------|
  // Doc time: 0---\/\/\/-------99-100-101-102-103-----
  //
  // At this point we should flush our restarts and early end the first interval
  // and start the second interval, giving us
  //
  // So our timegraph looks like:
  //
  //                                currentTime
  //                                    v
  //                                +---------------|
  //                            +---|
  // Doc time: 0---\/\/\/-------99-100-101-102-103-104-
  //
  var newTime = anim.getStartTime() + 0.5 * anim.getSimpleDuration();
  svg.setCurrentTime(newTime);

  // Finally we call beginElement again giving us
  //
  //                                currentTime
  //                                    v
  //                                    +---------------|
  //                                +---|
  //                            +---|
  // Doc time: 0---\/\/\/-------99-100-101-102-103-104-105-
  //
  // If, however, setCurrentTime failed to flush restarts out starting point
  // we do come to update the timegraph would be:
  //
  //                              beginElementAt
  //                                    v
  //                            begin="100s"
  //                                v
  //                            +---------------|
  // Doc time: 0---\/\/\/-------99-100-101-102-103-----
  //
  // And as soon as we encountered the begin="100s" spec we'd do a restart
  // according to the SMIL algorithms and a restart involves a reset which
  // clears the instance times created by DOM calls and so we'd end up with
  // just:
  //
  //                                currentTime
  //                                    v
  //                                +---------------|
  //                            +---|
  // Doc time: 0---\/\/\/-------99-100-101-102-103-104-
  //
  // Which is probably not what the author intended.
  //
