Redis OM .NET not indexing embedded model's property as sortable

Question

I am trying to implement simple sorting in my project where memory of the application is kept in Redis Stack. So far, most features work without too many complications. However, I have found one that might break some logic eventually: When a property is marked as sortable in the main object, OrderBy works without a hitch. However, when I attempt to sort by a property in the embedded object, Redis OM throws the following exception:

Property `Field1` not loaded nor in schema
Failed on FT.SEARCH yes-idx * LIMIT 0 100 SORTBY Field1 ASC

The code is as follows:

var _provider = new RedisConnectionProvider("redis://localhost:6379");
_provider.Connection.DropIndexAndAssociatedRecords(typeof(Yes));
await _provider.Connection.CreateIndexAsync(typeof(Yes));
var coll = _provider.RedisCollection<Yes>();

for (int i = 1; i < 11; i++)
{
    var no = new No() { Field1 = i, Field2 = i * 100};
    var yes = new Yes() { Id = i, NoField = no, Timestamp = DateTime.Now };
    await coll.InsertAsync(yes);
}
var timey = coll.OrderBy(x => x.Timestamp).ToList();
var earlier = timey.FirstOrDefault();
var later = timey.LastOrDefault();
Console.WriteLine($"{earlier.Id} came earlier");
Console.WriteLine($"{later.Id} came later");

var timey2 = coll.OrderBy(x => x.NoField.Field1).ToList(); //throws here
var earlier2 = timey.FirstOrDefault();
var later2 = timey.LastOrDefault();
Console.WriteLine($"{earlier2.Id} came earlier");
Console.WriteLine($"{later2.Id} came later");

[Document(StorageType = StorageType.Json)]
public class Yes
{
    [Indexed, RedisIdField] public int Id { get; set; }
    [Indexed(CascadeDepth = 2)] public No NoField { get; set; }
    [Indexed(Sortable = true)] public DateTime Timestamp { get; set; }
}

public class No
{
    [Indexed(Sortable = true)] public int Field1 { get; set; }
    [Indexed] public int Field2 { get; set; }
}

Any idea why it might not be indexing the sortable property of the embed? There isn't much information on embedded models in the documentation, most cases involve flat models. I may well be doing something wrong, but since Redis Stack is relatively new this could be a genuine bug for all I know.
