Steps to reproduce

Create a stream with 2 SUBTITLE tracks, without interstitials:

curl 'https://stitcher.mixwave.stream/session' \
  -H 'Content-Type: application/json' \
  --data-raw $'{"uri": "asset://3e57177f-aa7d-4e59-b174-133160cb7a1a"}'

Get the url from the response and play it with https://hlsjs-dev.video-dev.org/demo/. The first 8 seconds contain two text tracks, you can select them with the controls, they'll also appear.

Now, let's add an interstitial with a timeOffset > 0:

curl 'https://stitcher.mixwave.stream/session' \
  -H 'Content-Type: application/json' \
  --data-raw '{"uri":"asset://3e57177f-aa7d-4e59-b174-133160cb7a1a","interstitials":[{"timeOffset":10,"uri":"asset://3e57177f-aa7d-4e59-b174-133160cb7a1a"}]}'

Select a subtitle track when it did not reach the interstitial yet. The subtitle track is selected (& HLS.js API reflects the right state), but it's not shown.

Expected behaviour

Subtitles should be visible.

What actually happened?

Subtitles are not visible.
