Use a custom NewTarget prototype
info: |
SuppressedError ( error, suppressed, message )
1. If NewTarget is undefined, let newTarget be the active function object, else let newTarget be NewTarget.
2. Let O be ? OrdinaryCreateFromConstructor(newTarget, "%SuppressedError.prototype%", « [[ErrorData]], [[AggregateErrors]] »).
...
6. Return O.
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.
Return proto.
