Query includes wrong count and "null" with nested elements

APIs Content Delivery API

I have a content model with nested elements.

When I unpublish nested elements, the query results includes an error that some links are not resolvable - this is documented.

But it also includes “null” as elements and wrong element count - which included the unpublished item. This seems to me as wrong behaviour.

Result where I nested item is published and another unpublished:

Query:

 {
  testParentCollectionCollection
  {
    items
    {
      childrenCollection
      {
        total,
        items
        {
          testText
        }
      }
    }
  }
}

Response:
