  Error when advancing the provided iterable (rejecting promise)
info: |
  Promise.any ( iterable )

  5. Let result be PerformPromiseAny(iteratorRecord, C, promiseCapability).
  6. If result is an abrupt completion, then
    a. If iteratorRecord.[[Done]] is false, set result to IteratorClose(iteratorRecord, result).
    b. IfAbruptRejectPromise(result, promiseCapability).

  Runtime Semantics: PerformPromiseAny

  8. Repeat
    a. Let next be IteratorStep(iteratorRecord).
    b. If next is an abrupt completion, set iteratorRecord.[[done]] to true.
    c. ReturnIfAbrupt(next).
