The original implementation of the test for the absense of a [[PromiseState]] internal slot did not actually assert the documented semantics. Re-implement the test to rely on the IsPromise abstract operation (via `Promise.prototype.then`) to accurately ensure that the object does not have a [[PromiseState]] internal slot. In relying on the semantics of the `instanceof` operator, the original test for the [[Prototype]] internal slot was imprecise (the assertion could be satisfied if additional objects were incorrectly defined on the prototype chain). Re-write the test to assert the value of the [[Prototype]] internal slot directly. |
