  Target Milestone: ---

Is there any class that supports indexed getters that also has a member that
could be mistaken for an indexed getter?

Because that seems to be the only reason why we wouldn't return a property
descriptor for undefined here.

And the fact that we don't return a property descriptor for undefined here
actually creates a bug for the Window object, since its named properties are
looked up in a different algorithm on a different object. Having said that,
this bug will go away since we'll most likely move indexed property lookup to
the window proxy object so the Window object can become an "ordinary" object.
