| New items in the array are accessible via iteration until iterator is "done". |
| info: | |
| When an item is added to the array after the iterator is created but |
| before the iterator is "done" (as defined by 22.1.5.2.1), the new item's |
| value should be accessible via iteration. When an item is added to the |
| array after the iterator is "done", the new item should not be |
| accessible via iteration. |
