That is likely because (version 1) matroska files do not contain any keyframe
information in the block data, so outgoing buffers cannot be marked properly
that way, and the muxing matroskamux does not stand much of a chance then.

Seeking works in the original matroska because the index contains "seek points"
(which presumably then point to keyframes, though not necessarily all of them,
and these are likely to be found at cluster starts, but that is not certain
either ...).
