Behaviour of .prototype (and its relationship to further-delegating objects) isn't standardized anywhere -- why do you believe that we should have IE8's behaviour here, out of curiosity? This is a dup of something, I think related to getElementsByClassName, but I can't recall it off-hand.

I think now that getElementsByTagName shoudl return NodeList (not HTMLCollection) Konqueror, Safari, Opera, Chrome return NodeList. Only IE returns HTMLCollection. But FF NodeList also fails! if(!NodeList.prototype.indexOf)NodeList.prototype.indexOf=function(V,I){for(I=I||0;I<this.length;I++)if(this[I]===V)return I;return -1}

Assuming getElementsByTagName() was meant to return an HTMLCollection, then it would be the fact that HTML 5 defines HTMLCollection using Web IDL that would require particular behaviour of .prototype. (Web IDL admittedly isn't quite baked yet, but I think it's likely that requiring window.HTMLCollection.prototype be the collection object's [[Prototype]], and for the prototype object to be mutable like the test assumes, would survive.) I suppose someone would need to write a version of DOM Core using Web IDL to get similar requirements for NodeList (perhaps http://simon.html5.org/specs/web-dom-core will be that).
