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).
