It's fixed when you remove the rotate from the transform (uncomment line 49) or if you first explicitly define them as variables using @property. https://codepen.io/Sidstumple/pen/yyarOba 2206532 1 webkit-bug-importer 2026-05-01 03:16:10 -0700 <rdar://problem/176009605> 2209543 2 ahmad.saleem792 2026-05-10 18:03:00 -0700 Fixed in 312860@main *** This bug has been marked as a duplicate of bug 313300 ***
