description: >
Cannot tamper remainingElementsCount when an allSettledKeyed reject element
function is called before later calls.
info: |
PerformPromiseAllKeyed ( variant, promises, ctor, resultCapability, promiseResolve )
...
The onRejected closure:
...
1. Let activeFunc be the active function object.
2. If activeFunc.[[AlreadyCalled]].[[Value]] is true, return undefined.
3. Set activeFunc.[[AlreadyCalled]].[[Value]] to true.
