Using Projection with EF Core Azure Cosmos DB Provider - incorrect query execution.

[nagg-hash]

I am using HotChocolate(v12) with EF Core Azure Cosmos DB Provider (Microsoft.EntityFrameworkCore.Cosmos 6.0.8).
I am trying to use Projection and Filtering, but I see below problem with query formation,

Lets take below model as example

    public class Student
    {
        public string id { get; set; }
        public Name name { get; set; }
        public List<Subject> subjects { get; set; }
    }

    public class Name
    {
        public string fName { get; set; }
        public string lName { get; set; }
    }

    public class Subject
    {
        public string subjectId { get; set; }
        public string name { get; set; }
    }

and I have query class as below

    public class Query
    {
        [GraphQLName("getStudent")]
        [UseProjection]
        [UseFiltering]
        public IQueryable<Student> GetStudent([Service] StudentDbContext dbContext)
        {
            return dbContext.StudentData.AsNoTracking();
        }
    }

Refer below query formation in different scenarios

query {
    getStudent(where:{
    or:[{ id: { eq: "1" } }, { id: { eq: "2" } }]
  }){
    id
  }
}
In this case, it is forming the right query, so no issues here.

info: Microsoft.EntityFrameworkCore.Database.Command
      Container='Student', Partition='?', Parameters=[@__p_0=?, @__p_1=?]
      SELECT VALUE {"Id" : c["id"]}
      FROM root c
      WHERE ((c["id"] = @__p_0) OR (c["id"] = @__p_1))

query {
    getStudent(where:{
    or:[{ id: { eq: "1" } }, { id: { eq: "2" } }]
  }){
    id
    name {
      fName
    }
  }
}
but for this query, somehow it is selecting all fields.

info: Microsoft.EntityFrameworkCore.Database.Command
    Container='Student', Partition='?', Parameters=[@__p_0=?, @__p_1=?]
      SELECT c["id"], c, c["name"]["fname"]
      FROM root c
      WHERE ((c["id"] = @__p_0) OR (c["id"] = @__p_1))

query {
    getStudent(where:{
    or:[{ id: { eq: "1" } }, { id: { eq: "2" } }]
  }){
    id
    name {
      fName
    }
    subjects {
      name
    }
  }
}

In above query scenario, i don't see 'subjects' array is being considered in the query and also it is selecting all properties.

info: Microsoft.EntityFrameworkCore.Database.Command
      Container='Student', Partition='?', Parameters=[@__p_0=?, @__p_1=?]
      SELECT c["id"], c, c["name"]["fname"]
      FROM root c
      WHERE ((c["id"] = @__p_0) OR (c["id"] = @__p_1))

Is this the expected behavior?
or am I missing anything here?

Thanks
