Enabled by default ASS subtitles not shown (and workaround)

[Disonantemus]

Describe the bug

Subtitles are enabled by default are not shown when playing, seems to happen only with ASS subtitles.

Usual video output using ffprobe:

$ ffprobe -v 0 -select_streams s -show_entries "stream=codec_name : stream_tags=language" -of default=nw=1 file.mkv
codec_name=ass
TAG:language=eng

Steps 2 reproduce:

1. Go to any video in media library that has ASS subtitles (anime usually).
2. Click on play or thumbnail to play video (integrated player).
3. Wait/seek 4 dialog, no subs shown.
4. Press [CC] in media player, does show subtitle enabled (by default), show something like this:

   English [Full] - Default - ASS"

---

Workaround:

1. Disable sub
2. Enable again

I have similar issue that well organized external .ass file won't be recognized by Jellyfin. There is no CC menu in this case if I only have external .ass file as subtitle. I dont' kown why. Maybe related? jellyfin-server 10.9
