Not sure what exactly causes this, but the frequency of the leak goes down severely when there's not much stuff to do in ascension anymore, just idling so it could be a multitude of things.
when it happens, memory fills up with something called "mutation record" (image 1) (image 2 for reference of normal RAM usage), causing most cpu processing go towards garbage collection (image 3)
when it lags 98% of the processing goes to "incremental CC" (which seems to be a firefox thing not related synergism being an incremental on a .cc website lol), it makes the experience laggy and miserable.
Simply refreshing the tab does not fix it, need to close it and go to the website again for like 10-15 minutes free of lag before it comes back again.
if you have to any ideas for things to make the cause more clear, be free to share em. ill try them out when i have free time.
