Hi, this grid layout works fine in Firefox ans Chromium browsers: https://codepen.io/gunnarbittersmann/pen/OPRyObK The headings should be positioned above the first item of their section. In Safari (26.3 on macOS and iOS), all headings are stacked onto each other at the position of the last section heading, as it would look like in other browser without `anchor-scope` being set. May it be that `anchor-scope` doesn’t work well with `display: contents` on the same element?
