Created attachment 307379 [details] Example to reproduce the issue Check the attached example, the first "item" has "overflow: visible" and the "margin-left: 50%" is resolved properly. The 2nd item has "overflow: auto" and the percentage resolution changes. In Chrome and Firefox both cases have the same output.

I am able to reproduce this bug in STP 155 and get "current" output using attached output. While other browsers (Chrome Canary 108 and Firefox Nightly 107) match other and show "expected output". Thanks!

It seems to be fixed now - I am unable to reproduce it on Safari 18.3.1 on macOS 15.3.2.
