Using a custom playback range in the MRQ doesn't work if its the same as the original, but it has a camera cut track that differs in length

1. Create a sequence with a camera and camera cut track with section for the camera
2. Shorten the end of the camera cut section to frame 15
3. Open the sequence in the Movie Render Queue
4. In the output settings enable "Use Custom Playback Range"
5. Set the frame range to that of the sequence (default 0, 150)
6. Render the sequence

RESULT

Only the frames of the camera cut are rendered.
