Steps to reproduce

I've made a minimal reproduction in https://github.com/nickdbush/hls-repro. It includes reproduction steps, media segments, and console output.

Expected behaviour

The video thumbnail loads and the video can be played. This is what happens when running in Chrome on the some computer, or changing the m3u8 manifest to exclude some segments.

What actually happened?

No thumnail appears and the video does not load. The <video/> element remains blank.
