Description

The auto subtitles from youtube no longer work properly. Looking at the generated vtt and then converted ass subtitles the script is fully pulled, but it places the full script within the first few seconds (<5) in the subtitle files. This used to not happen, and does not seem to be caused by a change in yt-dlp since the behaviour changed without a change in yt-dlp. I have also tested and it does not seem to be a one off issue with this video, it seems to happen on all videos (only on auto generated subtitles not traditional subtitles).
