Created attachment 464410 [details] test case demonstrating the issue 1. 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.

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.
