Yeah, as long as we're focused on the really important things. Like animations that nobody actually needs or wants (apart from the person putting it there). That is, of course, until it ruins the user experience by bogging down the browser. And then, sure, let's debug that and make sure it runs on everyone's browser/os/cpu/gpu combo. That's a brilliant use of time.

Until someone turns up with a new combo where it doesn't work. Because judging by the comments, this seems to be a janky piece of code that isn't well understood.

"Turn it off" (or rather, "rip it out, and throw it away" is good advice. If there is even a slight chance this might come back to haunt you and screw the user experience, it isn't worth it. If your animation is more important than avoiding a horrible user experience, well, that's kind of useful for your customers I suppose.
