Two or more twitch streams cause excessive buffering

Description of the issue:
Having two or more Twitch streams open in two different tabs or windows makes both streams buffer and then not load at all. The higher the resolution the more pronounced the issue is.

Steps to Reproduce (add as many as necessary): 1. 2. 3.

  1. Open two Brave windows
  2. Load twitch in both windows
  3. Open any stream in both windows and set resolution to 1080p
  4. Issue occurs after a couple seconds at the latest

Actual Result (gifs and screenshots are welcome!):
I have recorded a video of the issue occurring:
