[feature request] improve compability for youtube-style `WEBVTT subtitles ( wvtt / vtt )` subtitles

https://github.com/yt-dlp/yt-dlp/issues/10796

is it possible to make the subtitles look the same in vlc? Currently, subtitles that define text and background color are overiden, and text that is multi line and fit the whole window are truncated.
