info: |
  1. Let promise be the this value.
  2. Return ? Invoke(promise, "then", «undefined, onRejected»).

  1. Assert: IsPropertyKey(P) is true.
  2. If argumentsList was not passed, let argumentsList be a new empty List.
  3. Let func be ? GetV(V, P).
  4. Return ? Call(func, V, argumentsList).
