  Error when accessing an iterator result's `value` property (not closing
  iterator)
info: |
  Promise.allSettled ( iterable )

  6. Let result be PerformPromiseAllSettled(iteratorRecord, C, promiseCapability).
  7. 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: PerformPromiseAllSettled

  ...
  6. Repeat
    ...
    e. Let nextValue be IteratorValue(next).
    f. If nextValue is an abrupt completion, set iteratorRecord.[[Done]] to true.
    g. ReturnIfAbrupt(nextValue).
