Twitch livestream quality gradually drops over time

What happened?

What happened:

So I was chilling watching LEC co-stream when I noticed stream looking worse but I paid no mind to it for a while because bitrate could have been overflown or something, however when quality dropped even further I started looking and found there are HttpProxy errors around the time quality would drop.

Steps:

1. Open a stable 1080p livestream
2. Manually select 284x160( yes qualities are reversed as pointed in: Video quality inside video player is reversed (Odysee). #191 )
3. Wait for Proxy error to happen (should look like the one in log output part)
   ...
4. Eventually arrive at 360p quality while player shows 284x160(1080p) is selected.

Expected behaviour:

To be honest best case if there is no need, quality shouldn't drop at all if there is enough buffer for the player to recover in time. If needed, player should try dropping quality until it manages to recover.

After how much time does the error occurs?

It seems random, had some "runs" where it would not drop for minutes but also had it happen within seconds of starting the stream. Once or twice it even managed to proc one immediately after another resulting in image quality going to low immediately.

Here is how the extreme example saved in logs:
