Created attachment 465775 [details] standalone html that explains the bug Latest Safari Version 16.4 (17615.1.26.101.9, 17615) When element has transform-style: preserve-3d set, then :after pseudo element with negative z-index always prevents links to be clicked. They are visible and all, rendered as in another browsers, but not clickable. In current Safari, also transformZ is buggy and does not move :after behind the element, this is fixed in current STP Release 166 (Safari 16.4, WebKit 17616.1.6.11), but links are not clickable still. Current effective workaround is to set pointer-events: none; for :after pseudo element. Current Chrome and Firefox are identical and work as expected in all cases. There is codepen that explains: https://codepen.io/atirip/pen/ZEqzVBV Attachment has standalone html.
