Sequencer UpdateTimeCursorPosition can set TimeCursorPosition beyond the end of the track when stopping

Sequencer UpdateTimeCursorPosition can set TimeCursorPosition beyond the end of the track when stopping

UDN
Description

After calling Stop() in UpdateTimeCursorPosition (LevelSequencePlayer.cpp:392), we continue on to set TimeCursorPosition to NewPosition. At this point, NewPosition is beyond the end of the track. A licensee has reported that this is causing problems with the event track.

Steps to Reproduce
  1. Play a track
  2. Wait for the track to reach the end and UpdateTimeCursorPosition to be called
  3. Stop will be called and LastCursorPosition will be set to 0 (the beginning of the track), but TimeCursorPosition will still be set to the new value (beyond the end of the track)
