Screengrab of the issue

::before and ::after pseudo elements are not included in the 3d rendering context extended by the parent element.



Steps to reproduce: 
1. Open test on https://johannesodland.github.io/browserbugs/2023/safari-3d-rendering-context-pseudo-element-issue.html

Expected result: 
Both borders in the test are drawn in the same position, with the red border hidden behind the green border. 


Actual result: 
The border of the ::before element is not participating in the 3d rendering context, and is not perspective transformed.
The borders of the two elements are drawn in different positions, and both are visible.

I am not able to reproduce this bug in Safari Technology Preview 169.

Can you try to see if this is reproducible for you in STP169?

Tested on TP169 now. The issue seems to be resolved.

Thanks for confirming. Marking this as "RESOLVED CONFIGURATION CHANGED", when it will land in Safari release version, I don't have any information. :-)
