Twitch Pre-Roll ads (even on audio_only) -- Yes, tested using git snapshot post "fix" #2368
Description
- This is a bug report and I have read the contribution guidelines.
The previously closed issue #2357 is still happening and I have reproduced it after manually installing a git checkout from about 10 min before this bug report.
Current test URL:
Even audio only (though the example was captured at another resolution)
streamlink twitch.tv/zisteau audio_only
Will display an actual VIDEO ad, also completely ignoring resolution or bandwidth use desires.
Occasionally the mismatch between the ad and the stream also causes the audio to playback in an oddly corrupted way (the streamer sounded down-pitch shifted, and the audio was very studdery, but that was a result of the ad invasion).

I also had streamlink dump a --stream-url and ran wget on the the result:

Some of the redacted streams appear likely to be either session or user-login specific, so to err on the safeside I've [REDACTED] them.
Of also note, the EXTINF date-stamp appears to be referencing one that is wildly divergent from current timestamps.
