      Steps to Reproduce

      In mongosh run the following commands:

      1. db.collection.createIndex({a: 1}, {v: 1})
      2. db.collection.getIndexes()

      Expected Results

      [
        { v: 2, key: { _id: 1 }, name: '_id_' },
        { v: 1, key: { a: 1 }, name: 'a_1' }
      ]

      Actual Results

      [
        { v: 2, key: { _id: 1 }, name: '_id_' },
        { v: 2, key: { a: 1 }, name: 'a_1' }
      ]

      Additional Notes

      The mongo shell built from "ninja install-devcore" still behaves as expected.
