//
// At this point we should flush our restarts and early end the first interval

// So our timegraph looks like:

// currentTime

// +---|
// 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.
