Audio-only live stream resumes using outdated buffer, then frequently fails

Platform:

• MacOS 11.6.5 (intel)

Versions tried:

• vlc-3.0.17.3-intel64-cb39c3b5
• vlc-4.0.0-dev-intel64-caf66c91

Procedure:

1. Create a playlist with an audio-only live stream URL, such as http://ais-sa3.cdnstream1.com/2606_128.aac the history of which can be found here: https://live.mystreamplayer.com/bagel
2. Begin playback in VLC and let it go for a few minutes.
3. Stop playback.
4. Wait a least five minutes.
5. Resume playback.
6. On rare occasions, playback resumes at the current point in live time. If so, wait a few minutes and return to Step 3.
7. If playback has resumed using the old buffer, let it continue.
8. After about 30 seconds, one of these things will happen:
   1. Fresh audio data will be fetched, and playback will suddenly catch up with "live" once more
   2. or playback will stop with errors like these in the log:

In my opinion, neither of the two outcomes in Step 8 is good. I think that if a live stream's buffer is several minutes out of date, it should be discarded before playback resumes.
