Error when call an iterator next step (rejecting promise)
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
a. Let next be IteratorStep(iteratorRecord).
b. If next is an abrupt completion, set iteratorRecord.[[Done]] to true.
c. ReturnIfAbrupt(next).

IteratorStep ( iteratorRecord )
1. Let result be ? IteratorNext(iteratorRecord).
IteratorNext ( iteratorRecord [ , value ] )
1. If value is not present, then
a. Let result be ? Call(iteratorRecord.[[NextMethod]], iteratorRecord.[[Iterator]], « »).
2. Else,
a. Let result be ? Call(iteratorRecord.[[NextMethod]], iteratorRecord.[[Iterator]], « value »).
