WebIDL: Can you explicitly pass undefined in as an argument for an optional parameter? Or will that exclusively look for an overload without any param period, and blow up if it doesn't find it?

I think it is valid (to pass undefined in an optional param), since we want passing undefined vs passing nothing to be treated the same generally, right?
