Contains on entity type with list typed as object fails to translate

Reported here: #20624 (comment)

Not a regression: also fails on 5, 6, 7, and 8.

var blog = new Blog();

using (var context = new AppDbContext())
{
    await context.Database.EnsureDeletedAsync();
    await context.Database.EnsureCreatedAsync();

    context.AddRange(new Post { Blog = blog }, new Post { Blog = blog });
    await context.SaveChangesAsync();
}

using (var context = new AppDbContext())
{
    var blogList = new List<object> { blog };
    var posts = await context.Posts.Include(e => e.Blog).Where(e => blogList.Contains(e.Blog)).ToListAsync();

    Console.WriteLine(context.ChangeTracker.DebugView.LongView);
}

public class AppDbContext : DbContext
{
    public DbSet<Blog> Blogs => Set<Blog>();
    public DbSet<Post> Posts => Set<Post>();

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
        => optionsBuilder
            .UseSqlite(@"Data Source=db.dat")
            .EnableSensitiveDataLogging();
}

public class Blog
{
    public int Id { get; set; }
    public string? Title { get; set; }
}

public class Post
{
    public int Id { get; set; }
    public int BlogId { get; set; }
    public Blog Blog { get; set; }
}

Unhandled exception. System.InvalidOperationException: Translation of 'EF.Property<int?>((Blog)ProjectionBindingExpression: EmptyProjectionMember, "Id")' failed. Either the query source is not an entity type, or the specified property does not exist on the entity type.

FWIW Containment with entity types (as opposed to scalars) needs some work, the older non-queryable design is still used there.
