My new reading of this new definitions of [[GetOwnProperty]] is that for
interfaces like HTMLCollection that do not OverrideBuiltins, both
built-in properties on the prototype and expando properties on the
collection itself hide named properties. I'd like to double-check that
this is intentional since Firefox and Chrome seem to have named
properties hide expandos.
