I have also seen this issue with WebM fragments in MSE support of
WebKitForWayland.

matroskademux receives the WebM elements in this order and in this state:

Element id GST_EBML_ID_HEADER, state GST_MATROSKA_READ_STATE_START 
Element id GST_MATROSKA_ID_SEGMENT, state GST_MATROSKA_READ_STATE_SEGMENT 
Element id GST_MATROSKA_ID_SEEKHEAD, state GST_MATROSKA_READ_STATE_HEADER 
Element id GST_EBML_ID_VOID, state GST_MATROSKA_READ_STATE_HEADER 
Element id GST_MATROSKA_ID_SEGMENTINFO, state GST_MATROSKA_READ_STATE_HEADER 
Element id GST_MATROSKA_ID_TRACKS, state GST_MATROSKA_READ_STATE_HEADER 
Element id GST_MATROSKA_ID_CUES, state GST_MATROSKA_READ_STATE_HEADER 


Element id GST_MATROSKA_ID_CLUSTER, state GST_MATROSKA_READ_STATE_HEADER 
Element id GST_MATROSKA_ID_CLUSTERTIMECODE, state GST_MATROSKA_READ_STATE_DATA 
Element id GST_MATROSKA_ID_SIMPLEBLOCK, state GST_MATROSKA_READ_STATE_DATA 
*
*
*
Element id GST_MATROSKA_ID_CLUSTER, state GST_MATROSKA_READ_STATE_DATA 
Element id GST_MATROSKA_ID_CLUSTERTIMECODE, state GST_MATROSKA_READ_STATE_DATA 
Element id GST_MATROSKA_ID_SIMPLEBLOCK, state GST_MATROSKA_READ_STATE_DATA 
*
*
*
Element id GST_EBML_ID_HEADER, state GST_MATROSKA_READ_STATE_DATA 
Element id GST_MATROSKA_ID_SEGMENT, state GST_MATROSKA_READ_STATE_DATA 
Element id GST_MATROSKA_ID_SEEKHEAD, state GST_MATROSKA_READ_STATE_DATA 
Element id GST_EBML_ID_VOID, state GST_MATROSKA_READ_STATE_DATA 
Element id GST_MATROSKA_ID_SEGMENTINFO, state GST_MATROSKA_READ_STATE_DATA 
Element id GST_MATROSKA_ID_TRACKS, state GST_MATROSKA_READ_STATE_DATA 
Element id GST_MATROSKA_ID_CUES, state GST_MATROSKA_READ_STATE_DATA


Element id GST_MATROSKA_ID_CLUSTER, state GST_MATROSKA_READ_STATE_DATA 
Element id GST_MATROSKA_ID_CLUSTERTIMECODE, state GST_MATROSKA_READ_STATE_DATA 
Element id GST_MATROSKA_ID_SIMPLEBLOCK, state GST_MATROSKA_READ_STATE_DATA 
*
*
*
Element id GST_MATROSKA_ID_CLUSTER, state GST_MATROSKA_READ_STATE_DATA 
Element id GST_MATROSKA_ID_CLUSTERTIMECODE, state GST_MATROSKA_READ_STATE_DATA 
Element id GST_MATROSKA_ID_SIMPLEBLOCK, state GST_MATROSKA_READ_STATE_DATA 
*
*

MatroskDemux ignores the element "GST_EBML_ID_HEADER" in
"GST_MATROSKA_READ_STATE_DATA" state, so it doesn't reset the streams parser
and doesn't parse the new EBML Header.
