For cases like HTMLPropertiesCollection.namedItem, which overrides
HTMLCollection.namedItem, we don't want to allow
HTMLCollection.prototype.namedItem to be called on an HTMLPropertiesCollection
object.

 <Hixie> if a method/setter/getter from a prototype of interface A is applied
to an object that is of an interface B that is a subclass of A, and B defines
its own method/getter/setter with the same name, then throw.
 <Hixie> by setters/getters i meant attributes
