passing correct newTarget parameter

7. If trap is undefined, then

b. Return ? Construct(target, argumentsList, newTarget).

|
|
|
Construct ( F [ , argumentsList [ , newTarget ] ] )
|
|

5. Return ? F.[[Construct]](argumentsList, newTarget).

5. If kind is "base", then

|
a. Let thisArgument be ? OrdinaryCreateFromConstructor(newTarget, "%ObjectPrototype%").

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.
