Same for me if I don't do anything on the page. But then if I actually scroll the page it gets exuberant. I think it's loading the same assets many times in parallel and possibly repeatedly. Also, "only", lol.

Look at this hilarious bucket of shit: https://i.imgur.com/36CBn5y.png And that's in Chrome!

Firefox actually handles this page's bullshit gracefully, by saying "NO! FUCK OFF, WEBPAGE!" ("Will-change memory consumption is too high. Budget limit is the document surface area multiplied by 3 (730032 px). Occurrences of will-change over the budget will be ignored.")
