[Bug 12299] The (normative and non-normative) assertion that tokenlist.item(index) / tokenlist[index] returns null for index>=length appears to be in conflict with WebIDL, at least for the index property case; afaict WebIDL requires that index property getters throw

Actually I think I might be wrong on what WebIDL requires; since corresponding
properties for indexes outside the range are never created, trying to access
such properties it will return undefined except in strict mode. Nevertheless
the specs are inconsistent here.
