Using Facebook in Brave causes uptick in resource usage over time for some users

[Brave-Matt]

Description

Some users have reported that while using Facebook in Brave, the site will eventually spike in memory usage resulting in poor performance. To resolve the issue, clearing cache/site data for Facebook works, but only temporarily. The issue appears to emerge again after a day or two of regular use.

This occurs in both stable and Beta builds.

Any update on that one here? These stall times and unresponsiveness is killing me and I'm really thinking about switching browsers.
