| Explicit iterator closing in response to error |

| info: | |
| 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 |
| ... |
| i. Let nextPromise be ? Invoke(constructor, "resolve", « nextValue »). |
