Chromium pauses at chunk boundaries when playing back mkv/webm AV1

When playing back a file encoded with rav1e and opus audio, chromium pauses at what appears to be each chunk boundary. Firefox and mpv play the video fine.

@tdaede I can't reproduce the issue, 9 chunks in this video. (WEBM played well in Chrome Version 92.0.4515.131 (Official Build) (64-bit)) Source Youtube AVC+ACC Encoded rav1e AV1 + OPUS MKV Copied to WEBM

Here is a source file that causes it: https://0x0.st/-yHs.mp4 Here is the resulting file: https://0x0.st/-yoF.webm Here is the av1an command line: ~/sandbox/Av1an/target/release/av1an --webm -v="--quantizer 200" -a="-c:a libopus -b:a 64000" -e rav1e -i td-crt-vcf-2021/td-crt-vcf-2021.mp4

Plays just fine for me
