fragLoadPolicy is not followed if level has 2+ gaps fragments in a row

What version of Hls.js are you using?

v1.5.15

What browser (including version) are you using?

What OS (including version) are you using?

macOS Sonoma 14.6.1

Test stream

Provided in demo GitHub repository

Configuration

{}

Additional player setup steps

I simplified the demo, but the thing I am trying to achieve here is to make all failed fragments "skippable", so I am trying to set them as a GAP fragment with this code:

hls.on(Hls.Events.ERROR, (event, data) => {
  console.log(event, data);
  if (data.details !== Hls.ErrorDetails.FRAG_LOAD_ERROR) return;
  if (!data.fatal) return;
  console.log('Setting Fragment as a GAP', data.frag);
  data.frag.gap = true;
  data.frag.tagList.unshift(['GAP']);
  hls.startLoad();
});

I want to make Hls.js follow fragLoadPolicy for all requests it does to load fragments, so this code can work properly.

Checklist

• The issue observed is not already reported by searching on Github under https://github.com/video-dev/hls.js/issues
• The issue occurs in the stable client (latest release) on https://hlsjs.video-dev.org/demo and not just on my page
• The issue occurs in the latest client (main branch) on https://hlsjs-dev.video-dev.org/demo and not just on my page
• The stream has correct Access-Control-Allow-Origin headers (CORS)
• There are no network errors such as 404s in the browser console when trying to play the stream

Steps to reproduce

1. Clone demo repository https://github.com/zalishchuk/hlsjs-gap-demo
2. Run the mock server
3. Go to http://localhost:3000 to see the described behaviour

Expected behaviour

Fragment requests after gap fragments should follow fragLoadPolicy and make retries, then after all retries are used must pop with fatal FRAG_LOAD_ERROR

What actually happened?

Fragment requests after gap fragments are not following fragLoadPolicy and are not making any retries, so FRAG_LOAD_ERROR never pops
