See http://code.google.com/p/chromium/issues/detail?id=80591 for more details of the case that keeps biting them. Also see http://lists.w3.org/Archives/Public/public-webapps/2011AprJun/0389.html and http://lists.w3.org/Archives/Public/public-script-coord/2012JanMar/0010.html for discussion on standardizing this. The discussion is not quite done, but it seems likely the WebKit/JSC/V8 will need to change. 537227 1 gregsimon 2012-01-17 11:27:13 -0800 I looked at a CL for this bug and yes it does require a v8 change for v8-based webkit browsers. 544462 2 ojan 2012-01-27 15:48:47 -0800 OK. This is resolved now. http://lists.w3.org/Archives/Public/public-script-coord/2012JanMar/0104.html 609231 3 arv 2012-04-24 16:35:29 -0700 V8 has fixed this (behind a flag) but since all WebIDL attributes are implemented as own properties on the global object we need to fix bug 49739 to get non configurable properties to work correctly. 610071 4 arv 2012-04-25 14:59:33 -0700 The ES5.2 behavior is at https://bugs.ecmascript.org/show_bug.cgi?id=78 701846 5 arv 2012-08-22 06:32:45 -0700 Chrome is now shipping with this behavior.
