How do I avoid nulls in array after delete mutation with React Relay?

Question

Using react-relay v15.

I have a component that gets a list of orders.

const data = useLazyLoadQuery<OrdersQueryType>(OrdersQuery, {});

I have another component that can delete orders via a mutation.

mutation DeleteOrderMutation($orderId: ID!) {
  deleteOrder(input: { orderId: $orderId }) {
    order {
      id @deleteRecord
    }
  }
}

If the data originally had three orders in it, after the mutation runs, it has 2 orders in it, and a null element where the deleted order was.

Can this be avoided so that the array only has two entries? Adding null checks for arrays contents is not ideal.
