Alternative way to work sort and first together of nested items when using edges

This issue was reported by a user at SLB where they encountered an unexpected behavior when sorting the runHistory field in GraphQL. It appears that the sorting might not be applied as expected when using first: 1 in the query.

type Workflow {
  runHistory: [WorkflowRun]
}

type WorkflowRun {
  endTime: Timestamp
}

query MyQuery {
  listWorkflow {
    items {
      runHistory(sort: {endTime: DESC}, first: 1) {        
        items {
          endTime
        }
      }
    }
  }
}

By running the above query, he expects the first WorkflowRun in runHistory to be the most recent. If the user changes first: 1 in the query to first: 10 then he's able to see WorkflowRun in descending order.
