Comment (by MaxEliaserAWS):

 Correct, no issue with playback, and no issue with PTS/DTS, only with the
 timecodes. The only user-visible symptom would be in the ffprobe output as
 I have described.

 We are using ffprobe in our test automation to ensure that the GOP
 timecodes in our files are correct. If electing not to fix the issue, that
 is fine, I can just configure the test to look on frame 89 instead of 90--
 I just needed to file a ticket I can reference as to why the test is
 written that way.
