Go the testcase with a wide viewport in Safari Expected: the square is green Actual: the square is red. Firefox and Chrome displays green. PS: also opened on https://github.com/webcompat/web-bugs/issues/116472 This has a real consequence on the readability of this site http://d5f.org/en This is probably a site mistake, but there is still a behavior difference in between Safari and Chrome/Firefox on the other side. 1923919 1 webkit-bug-importer 2023-01-08 00:37:47 -0800 <rdar://problem/103999798> 1923998 2 m_dubet 2023-01-09 00:26:32 -0800 This is broken in STP and trunk indeed (it works on stable Safari). The parsing seems correct (with or without the CSS nesting experimental flag). (I've added a small snippet to check it: <script> var rule = s.sheet.cssRules[1]; l.textContent = rule.cssText; </script> ) It seems to be a media query evaluation issue. 1924383 3 koivisto 2023-01-10 05:22:42 -0800 rdar://103732686 1924391 4 koivisto 2023-01-10 06:00:13 -0800 Pull request: https://github.com/WebKit/WebKit/pull/8457 1924503 5 ews-feeder 2023-01-10 10:12:10 -0800 Committed 258732@main (3e90af4d3b34): <https://commits.webkit.org/258732@main> Reviewed commits have been landed.
