Check out the following example in Safari v15.1 (17612.2.9.1.20) https://codepen.io/pollx/details/jOGqByv And this is the result in the different browsers: Chrome v96.0.4664.55 https://i.stack.imgur.com/HWyoy.png Firefox v94.0.2 https://i.stack.imgur.com/9lrF1.png Safari v15.1 (17612.2.9.1.20) https://i.stack.imgur.com/6ZMju.png Can someone exaplin the differences in Safari v15?
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.
