Child subgraph shows UID when parent subgraph shows UID

[jchiu0]

Consider the query

{
  me(_xid_: m.06pj8) {
    type.object.name.en
    film.director.film(first:2)  {
      _uid_
      film.film.genre {
        type.object.name.en
      }
      type.object.name.en
      film.film.initial_release_date
    }
  }
}

Here is a snippet of the reply:

               {
                    "_uid_": "0xc6f4b3d7f8cbbad",
                    "film.film.genre": [
                        {
                            "_uid_": "0x7ab7e3d640ac359",
