Comment (by stichnot):

 The issue appears to be an off-by-one mismatch in frame numbering, in the
 case of seeking to a specific frame number versus querying the number of
 the most recently rendered frame.  In the original code, this results in
 continually asking to seek to the same frame.  I suspect that the 'Remove
 the "Seek to exact frame" setting' commit made the logic more rigorous and
 exposed a preexisting issue in the experimental commflagging code.

 Apart from that, it's a nice find that we can greatly speed up next-frame
 seeking by avoiding actual seeking.
