Does it work on Firefox?
It does. I found a workaround. but it required changing settings. Librewolf is a little too secure for some websites to work correctly it seems.
At the left side of the URL bar you can see an Image icon, it's for manualy enable canvas usage for a specific website. Don't turn it off globally in about:config.
