I suspect this was not intentional, but rather the result of copying a
flac stream into mkv without any special treatment for the metadata.
Thus it just got copied as-is along with the real CodecPrivate data
since they're stuck together in the source file. I doubt this practice
is encouraged by the Matroska developers and I wouldn't be surprised
if they discourage demuxers from reading this data, since it's in the
wrong place.. Someone authoring a proper MKV file should put this info
in the MKV metadata tags...
