I have checked https://codepen.io/pollx/details/jOGqByv on Ubuntu 12.10 with gtk port minibrowser and it looks that it shows the same behavior with chrome/firefox on Ubuntu 12.10.

I can't check this on Mac for now because I don't have Mac in the office, 
but I guess it's related with some Mac port-specific factor.

Thanks for filing, I see no difference between the other browsers and Safari Technology Preview (Safari 15.4). Seems to be resolved on latest.
