Seems to break in all cases where macOS hardware decoding is involved. Using software decoding in an Ubuntu VM, I get a hiccup in the video but nothing fatal. On Windows using NVDEC I get completely clean playback; this is consistent with the original encoder being NVENC.

EDIT: My encoder settings for this stream, just in case that matters. 12 Mbps 4k60 with B-Frames disabled.
EDIT 2: Shaka Player and Bitmovin's HLS Player seem to run into this issue as well. But THEOplayer doesn't! Fascinating.
