CEA-608 text track is not made available through hls.js (works on theoplayer) #6457

What version of Hls.js are you using?

1.5.8

What browser (including version) are you using?

Google Chrome Version 125.0.6422.112 (Official Build) (64-bit)

What OS (including version) are you using?

Test stream

https://www.rmp-streaming.com/test/hls/29052024/playlist.m3u8

Configuration

{
  "debug": true,
  "enableWorker": true,
  "lowLatencyMode": true,
  "backBufferLength": 90
}

Checklist

Steps to reproduce

Play HLS stream https://www.rmp-streaming.com/test/hls/29052024/playlist.m3u8 at https://hlsjs.video-dev.org/demo/ >> No text track is available.

Expected behaviour

This is a HLS stream with CEA-608 RollUp Text, hls.js should pick up on the text track. This does work on Theoplayer tester at https://www.theoplayer.com/test-your-stream-hls-dash-hesp with the same HLS stream.

What actually happened?

video.textTracks and hlsJS.allSubtitleTracks and hlsJS.subtitleTracks are all empty. hls.js is not picking up on the text track.
