    [[Prototype]] defaults to %WeakRefPrototype% if NewTarget.prototype is not an object.
  info: |
    WeakRef( target )
  
    ...
    3. Let weakRef be ? OrdinaryCreateFromConstructor(NewTarget,  "%WeakRefPrototype%", « [[Target]] »).
    4. Perfom ! KeepDuringJob(target).
    5. Set weakRef.[[Target]] to target.
    6. Return weakRef.
  
    OrdinaryCreateFromConstructor ( constructor, intrinsicDefaultProto [ , internalSlotsList ] )
  
    ...
    2. Let proto be ? GetPrototypeFromConstructor(constructor, intrinsicDefaultProto).
    3. Return ObjectCreate(proto, internalSlotsList).
  
    GetPrototypeFromConstructor ( constructor, intrinsicDefaultProto )
  
    3. Let proto be ? Get(constructor, 'prototype').
    4. If Type(proto) is not Object, then
      a. Let realm be ? GetFunctionRealm(constructor).
      b. Set proto to realm's intrinsic object named intrinsicDefaultProto.
    5. Return proto.
