WebKit fails IETC Override_Property_Getter_High (both JSC and V8) http://samples.msdn.microsoft.com/ietestcenter/dominheritance/showdominheritancetest.htm?Override_Property_Getter_High Passes in FF. There seem to be a number of Object.defineProperty bugs on file, maybe this is just a dupe of one of them. The test is doing the following: Object.defineProperty(HTMLHeadElement.prototype, "profile", { get: function () { return "myProfile"; } }); var head = document.createElement("head"); if ("myProfile" == head.profile) alert("pass"); CCing the JavaScript ninjas.
See also bug 76107 which is about the "setter" variant of this test.
@Alexey - is this applicable anymore?

Redefinition of DOM properties is heavily covered by both WPT and our tests.
