description: >
Iterator is not closed when the "resolve" capability returns an abrupt
completion.
info: |
...
3. Let promiseCapability be ? NewPromiseCapability(C).
...
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).
8. Return Completion(result).
Runtime Semantics: PerformPromiseAllSettled
...
6. Repeat
...
d. If next is false, then
...
iii. If remainingElementsCount.[[Value]] is 0, then
1. Let valuesArray be CreateArrayFromList(values).
2. Perform ? Call(resultCapability.[[Resolve]], undefined, « valuesArray »).
IfAbruptRejectPromise
1. IfAbruptRejectPromise(value, capability).
