Reading about it, that ironically seems to be the exact problem Safari has. I mean the page "works" in Safari it's just you get these really random delays to the start of some of the sounds with all sorts of web discussion threads saying different ways to mitigate it on different platforms. I don't really fault them for having the goal to publish a paper and go the extra bit to make a friendly but imperfect webpage instead of being website creators who happen to publish papers on the side.
