Both FA and IB have integrated Ruffle - the latter with nightly updates. Its issue tracker is full of people trying to use the browser extension/addon version on e621, only the content security policy there forbids it - site owners need to add 'unsafe-eval' to CSP headers to make Ruffle work on Chrome/Webkit (there's plans to have a more limited 'wasm-unsafe-eval', but it isn't done yet).
There was one such report relating to Inkbunny prior to integration - predictably, regarding Babysitting Cream. None for Fur Affinity, at least not related to this issue, because they haven't enabled protection from scripting attacks via CSP.
