When Both AnimMontage and AnimationTrack are Playing, the Blending Results are Different from Expectation

When Slot animation by AnimMontage and AnimationTrack is done at the same time, the blend result differs from expectation.

Probably because if AnimMontage's loop playback by EventTrack is executed, that AnimMontage will affect the subsequent animation control result by AnimationTrack. For example, stopping AnimMontage with EventTrack before control by AnimationTrack does not cause this problem.

1. Add EventTrack to Sequencer to play looping AnimMontage
2. Added Section of AnimationTrack where Blend curve was adjusted after added EventTrack
3. Play
