Desktop Facebook website uses too much CPU

Description of the issue:
Opening messenger turns my CPU utilization up too much (compared to any other browser)

How can this issue be reproduced?

  1. Open Facebook on desktop
  2. Open messenger and talk to a friend

Expected result:
Cpu utilization stays low, comparable to other browsers.

Brave Version( check About Brave):

Additional Information:

Brave just turned my PC into a stove for no reason so I decided to upload an image of my task manager.


The one with the arrow is a facebook tab that has a single messenger window open.
The other is youtube.
My PC specs are RTX 4070, M.2 Gen 4 SSD and Ryzen 7 7800X3D.
I know nobody uses facebook anymore but I still do sadly. Is there any way to fix this?

I tried enabling and disabling HW acceleration, i tried many things. Any other browser behaves correctly and the issue only happens if I open a messenger window on the facebook page.
