Iterator is not closed when the "resolve" capability returns an abrupt

|
completion.
|

info: |

Let C be the this value.
|

|
|
Let promiseCapability be ? NewPromiseCapability(C).
|

Let iteratorRecord be GetIterator(iterable).

IfAbruptRejectPromise(iteratorRecord, promiseCapability).
|

|
|
Let result be PerformPromiseAny(iteratorRecord, C, promiseCapability).
|

If result is an abrupt completion, then
|
||
|
|
If iteratorRecord.[[Done]] is false, set result to IteratorClose(iteratorRecord, result).
|

IfAbruptRejectPromise(result, promiseCapability).
|

Return Completion(result).
