Getting specific items from a pubsub node copies the request items into the result packet, which produces an invalid result
Getting a specific list of items from a node has an error in which it copies the input list into the result and then retrieves the results from the node. Thus the reply is double the size with each item appearing twice, once without the payload and once with. This also results in requests with max_items set to return that attribute in the result as well.
