Aggregate function on owned type fails in EF8

[DnikitaA]

Bug description

Code below works in EF Core 6.0. But failed on EF Core 8.0.

I found the same issue #29201, but it was closed. The solution that was proposed only works with the Sum method.

Your code

using Microsoft.EntityFrameworkCore;

namespace GroupOwnedFields;

[Owned]
public class Period
{
    public DateTime Begin { get; set; }

    public DateTime End { get; set; }
}


public class Point
{
    public int Id { get; set; }

    public int OwnerId { get; set; }

    public DateTime DateTime { get; set; }

    public required Period Period { get; set; }
}

public class AppDbContext : DbContext
{
    public DbSet<Point> Points { get; set; }

    public AppDbContext()
    {
    }

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        optionsBuilder.UseSqlServer("Data Source=localhost;Initial Catalog=Test;Persist Security Info=True;User ID=test;Password=test");
        optionsBuilder.EnableSensitiveDataLogging();
    }
}

public class Program
{
    public static void Main(string[] args)
    {
        using var context = new AppDbContext();
        var query = context.Points
            .GroupBy(e => e.OwnerId)
            .Select(g => new
            {
                TotalCount = g.Count(),
                PastCount = g.Count(e => e.Period.End < DateTime.UtcNow)
            });
        var queryText = query.ToQueryString();
    }
}
