We should change this too.

I considered changing here unnecessary as this is the wrapping for when
intermediate properties are created.

[Manish Jethani, 2019/03/29 14:57:10]

Well so if an intermediate property is a function it should still work, right?

[hub, 2019/03/29 15:36:02]

I was wondering "why would someone do that" but then JavaScript is the answer.

Done. And added test case as well.

       wrapPropertyAccess(newValue, property, descriptor);
   };
 
   Object.defineProperty(object, name, {
     get: () => value,
     set: setter,
     configurable: true
   });
 }
