description: >
  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.
