[cssom] What does Element.pseudo() return when there's no corresponding pseudo-element?

http://dev.w3.org/csswg/cssom/#extensions-to-the-element-interface
describes an Element.pseudo() method.  It's not clear to me what
this returns when the pseudo-element isn't generated (in other
words, when the 'content' property [1] computes to 'none')

Should it return null, or should it return an PseudoElement object
whose style, when queried, shows a computed value of 'content:none'?
