Firefox sidebar causes extreme logging on some pages, leading to a noticeable performance issue

[MTRNord]

Hi I am using promnesia for firefox and in the chat app develop.element.io specifically I am getting lots and lots of logs which seems to not only cause UI blocking for the tab but also quite a high memory usage. I confirmed that turning off promnseia fixes the performance issues, which is why I think this may be a bug here.

There is an endless stream of these logs happening. It seems to specifically only be an issue with this page for reasons I dont get currently.

I am happy to provide any more info needed to debug this :)
