The Selectors API querySelector and querySelectorAll methods won't match uppercase class names in quirks mode. e.g. Try running this script in quirks mode. <p class="FOO"></p> <script> var p = document.querySelector(".FOO"); document.write(p ? "PASS" : "FAIL"); </script> The same script works correctly in standards mode.

note, this also affects getElementsByClassName in quirks mode

I can't reproduce this (I pasted the provided testcase into a document and loaded it in safari 4 beta, and it said PASS, same with r40738).

Created attachment 461503 [details] Quirk Mode - Test Case I changed the test case from Comment 0 in JSfiddle below: Link - https://jsfiddle.net/6r9odj5x/show All browsers (Chrome Canary 106, Firefox Nightly 105 and Safari 15.6 on macOS 12.5) are saying "PASS" for the test case, I am going to mark this as "RESOLVED CONFIGURATION CHANGED" Even with above "Quirk Mode" test case, all browsers are showing "PASS". Thanks!
