If shot track ends short of the Master Sequence length, all actors return to default state

If shot track ends short of the Master Sequence length, all actors return to default state.

This becomes an issue when you need the actors manipulated in Shot 1 to maintain their "end state" into shot 2 and even afterwards during gameplay.

1. Create a Master Sequence with 1 Shot
2. In the master sequence, move the end of the shot about 1 second past the end of shot 1 (see screenshot attached)
3. In the shot sequence, move a mesh in the level over the duration of the shot
4. Enable Auto-Play on the Master Sequence Level Actor
5. PIE

Result: At the end of play, the mesh moves back to it's default position. If Step 2 had left the master sequence length exactly at the end of the shot, this would not happen.
Expected: Mesh remains at it's last location.
