Comment (by MarkZV):

 Using FFmpeg to produce Ogg Vorbis from this input file, using either the
 FFmpeg native vorbis encoder or the libvorbis encoder, has the same issue.
 I'm not aware of a utility that checks the granule position consistency
 for Ogg Vorbis files but I just checked it manually.  Also different
 utilities displayed different timestamps for the packets in the resulting
 file depending on whether it computed them going forward or backward.  The
 timestamps should be the same either way.
