Looks like there's an issue remuxing sn 5 AVC. For some reason it contains samples that overlap with the previous segment. After adjusting the timestamps, the appended mp4 does not extend the buffer:

[log] > [stream-controller]: Loading fragment 5 cc: 0 of [0-21] level: 0, target: 24
[log] > [stream-controller]: IDLE->FRAG_LOADING
[warn] > AVC: 67 ms (-6000dts) overlapping between fragments detected
[log] > Video: First PTS/DTS adjusted: 24000/23933, delta: -67 ms
[log] > [stream-controller]: FRAG_LOADING->PARSING
[log] > [stream-controller]: Loaded fragment 5 of level 0
[log] > [transmuxer.ts]: Flushed fragment 5 of level 0
[log] > [stream-controller]: PARSING->PARSED
[log] > [stream-controller]: Buffered main sn: 5 of level 0 [0.000,23.867]

Avoiding the timestamp rewrite in this situation results in the media appending correctly #4977
