"Attribute typename not found" on connection using the filter "typename"

[angrykoala]

Given the type definition:

    interface Production {
        title: String!
    }

    type Show implements Production @node {
        title: String!
    }

    type Movie implements Production @node {
        title: String!
        actors: [Actor!]! @relationship(type: "ACTED_IN", direction: IN, properties: "ActedIn")
    }
    type Actor @node {
        name: String!
        ratings: [Int!]!
        lastRating: Int
        movies: [Movie!]! @relationship(type: "ACTED_IN", direction: OUT, properties: "ActedIn")
    }

    type ActedIn @relationshipProperties {
        year: Int
    }

A query with a connection, using the typename filter fails with the error "Attribute typename not found":

query TopLevelCount {
  productionsConnection(where: { typename: [Movie] }) {
    edges {
      node {
        title
      }
    }
  }
}

Epected behaviour

The operation should be equivalent to the (working) non-connection endpoint:

query TopLevelCount {
  productions(where: { typename: [Movie] }) {
        title
  }
}
