What version of Hls.js are you using?

v1.5.20

What browser (including version) are you using?

Zen Browser 1.8.2b (Firefox 135.0.1) (64-bit), also tested on Firefox 135.0.1 (64-bit)

What OS (including version) are you using?

Linux

Test stream

https://media.ashhhleyyy.dev/aaaaa/hls/aac_high_ended.m3u8

Configuration

{
  enableWorker: false,
}

Additional player setup steps

No response

Checklist

Steps to reproduce

  1. Load the above stream (which has an error as the first segment file contains no data) with enableWorker set to true.
  2. Observe that the stream loads correctly, though the first few seconds are not playable
  3. Change enableWorker to false (for example by importing hls.js as an ES module without workerPath configured)
  4. Observe in the developer tools that the first segment is being continually fetched (which does not happen when enableWorker is true

Expected behaviour

Running with enableWorker: false to not fetch the same segment repeatedly

What actually happened?

Disabling the worker causes continual fetching of the same segment
