                    ]
                }
            }
        }
    }
]

      We're seeing a differing result between v7.0 with optimizations off and master with optimizations on.

      The former returns

      {_id: null, num: {$numberDecimal: Infinity}}

      While the latter returns

      {_id: null, num: {$numberDouble: Infinity}}
