In the "Rules for handling parsing errors" section of the CSS specs it mentions: "User agents must close all open constructs (for example: blocks, parentheses, brackets, rules, strings, and comments) at the end of the style sheet." So I understand from this paragraph that the new behavior is the desired one (actually no browser supports the test case you attached as all of them look for the matching closing parenthesis till the end of the stylesheet). Adding some more experienced people so we could have another opinion. 1892634 6 ahmad.saleem792 2022-08-20 06:21:31 -0700 I am unable to reproduce this bug in Safari Technology Preview 151 and it does not show "red" border and it is same across all other browsers (Chrome Canary 106 and Firefox Nightly 105). I am going to mark this as "RESOLVED WONTFIX" since all browsers are aligned. Please reopen if you think this is still not correct intended beahvior or I am testing incorrectly.
