It looks like the page is trying to do feature detection, and is serving up un-prefixed 'transform' properties now. I'm not sure why. 318508 1 simon.fraser 2010-12-07 17:01:55 -0800 The real issue is: SyntaxError: Invalid regular expression: invalid range in character class: Beautifying the source, I see failures relating to the following lines: bO = bO.replace(/#[\w-_]+/, aA); bO = bO.replace(/(?:::|:|\.)[\w-_()]+|\[.*?\]/, aA); 318509 2 simon.fraser 2010-12-07 17:02:37 -0800 <rdar://problem/8741502> 318954 3 barraclough 2010-12-08 12:55:56 -0800 The problem here is that /[\w-_]/ is technically invalid, and we've been experimenting with slightly closer conformance to the spec in our regex engine. This appears to be breaking the web, so we'll be relaxing our interpretation of these rules again soon. cheers, G. 319263 4 barraclough 2010-12-08 21:52:08 -0800 This should be fixed in r73594. *** This bug has been marked as a duplicate of bug 50483 ***
