The demuxer works as expected? How many cycles uses for decoding, less
than mkv? If yes I'd move to other questions, since the target is reached.

Since is a corner case the possibilities are:
1- redefine the spec and point out that issue.
2- spend more time on the issue to get about a 1/4 improvement for a
feature probably 1/10^6 files will use and for which tar probably does a
quite better job...
