That's not correct.  For nullable types, ES undefined is converted to 
IDL null per step 3 of 
<http://dev.w3.org/2006/webapi/WebIDL/#es-nullable-type>.  There's some 
extra complexity there around DOMString in step 1, but it only applies 
when [TreatUndefinedAs] is used, which it's not in this case.
