      Summary

      ExpressionNotSupportedException thrown when .First() is used with a predicate when building SortDefinition.

      Using 2.19.1 driver with 5.0.23 server.

      How to Reproduce

      SortDefinition<Order> sortDefinition1 = Builders<Order>.Sort.Ascending(c => c.Items.First(x => x.Type == "XYZ").Rate);
      SortDefinition<Order> sortDefinition2 = Builders<Order>.Sort.Ascending(c => c.Items.First().Rate);

      The first one throws an exception when executed but the second one works as expected.
