FFMPEG demuxer seek error in Chrome range slider with AWS audio file

I’m encountering an issue where if you click or slide enough on a range slider in Chrome, it will eventually stop working and give this error, an error 2 (network error):

PIPELINE_ERROR_READ: FFmpegDemuxer: demuxer seek failed

If I google this error, I only find the Chrome source code:

Line 1749 of Chrome source code

First, this issue only happens in Chrome, not Firefox. Second, I can only get it to happen with an encrypted file from AWS, which I can’t get into a sandbox, so the sandbox I made will never encounter that error with the random audio file I used.

Here’s the sandbox.

The only difference I can find between this code and the failing code is the source of the audio file (AWS).
