Error when advancing the provided iterable (not closing iterator)

info: |
|

Promise.any ( iterable )

|
|
5. Let result be PerformPromiseAny(iteratorRecord, C, promiseCapability).
|
|
6. 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: PerformPromiseAny
|
|
|
|
8. Repeat
|
|
a. Let next be IteratorStep(iteratorRecord).
|
|
b. If next is an abrupt completion, set iteratorRecord.[[done]] to true.
|
|
c. ReturnIfAbrupt(next).
