I was sure this has been a thing for a while, either that or safari has a UI bug since forever.

I regularly get the wrong favicon in specific sites, for example ars technica favicon in reddit

Safari has super long lived favicon caches too. The only way to force a rebuild is to set your system clock forward a few years.

According to the Github page, you can just run `rm ~/Library/Safari/Favicon Cache/*`
