        Amazingly we got this far w/o needing self closing.
        The LegacyHTMLTreeBuilder clearly uses the self-closing
        state, but the fact that we never exposed it seems to
        not have caused any test failures.  Sad.

        The new HTMLTreeBuilder only needs the self closing state
        for foreign content mode (and a few parse error cases).
