  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).
