You just broke it in the non-fragment case now! As far as I can tell, 
there will never be a "input", "keygen", or "textarea" in scope, so the 
fragment case if condition will always be true and the token will always 
be ignored. I guess we want to ignore it if the stack of open elements 
does not have a "select" element in table scope.
