  Cannot tamper remainingElementsCount when two Promise.any Reject Element Function are called in succession.
info: |
  Let result be PerformPromiseAny(iteratorRecord, C, promiseCapability).

  Runtime Semantics: PerformPromiseAny

  ...
  Let remainingElementsCount be a new Record { [[value]]: 1 }.
  ...
  8.d ...
    ii. Set remainingElementsCount.[[value]] to remainingElementsCount.[[value]] − 1.
    iii. If remainingElementsCount.[[value]] is 0,
      1. Let error be a newly created AggregateError object.
      2. Perform ! DefinePropertyOrThrow(error, "errors", Property Descriptor { [[Configurable]]: true, [[Enumerable]]: false, [[Writable]]: true, [[Value]]: errors }).
      3. Return ThrowCompletion(error).
  ...

  Promise.any Reject Element Functions
  ...
  Let alreadyCalled be the value of F's [[AlreadyCalled]] internal slot.
  If alreadyCalled.[[value]] is true, return undefined.
  Set alreadyCalled.[[value]] to true.
