Skeletal Mesh gets stuck in T-Pose when using sequencer animation track with animation blueprint

If an actor that is set up to use an anim blueprint is used in the sequencer, then a property on the skeletal mesh is changed in the sequencer details panel. The actor will not evaluate any animation. If you change the character to force custom mode, no issue occurs.

1. Create new sequence with actor that has an animation blueprint as the animation instance.
2. Add actor to sequencer.
3. Add an animation track.
4. Add an animation sequence to the sequence track
5. Move playhead over the animation section
6. Edit any property on actor
7. Move playhead again
8. Skeletal mesh gets stuck in t-pose until change a property while playhead is not over animation section
