A query to contentNodes does not populate nodes in the return.

To reproduce, run a query:

query ThisIsBroken {
  contentNodes {
    nodes {
      ... on SimpleProduct {
        id
        name
        sku
        width
        weight
        uri
      }
    }
  }
}

The expected outcome would be to get populated fields.
