I don't think this is a WebIDL issue really.
Given the inconsistencies that it introduces in that a property
appears on documentElement, but isn't actually associated with the
element, and the fact that people will have to wrote the longer syntax
"document.documentElement.undoManager" rather than
"document.undoManager", I think it's better to just expose it on the
Adding things to the Window object is always iffy as that's the global
object, adding things to Document isn't really a big deal IMHO.
