Description
When I attach an entity that has an owned type attached to it and I change the state of that entity using the ChangeTracker to EntityState.Added, the owned type should also get the EntityState.Added state, but it doesn't.
Exception message: The entity of 'Entity' is sharing the table 'Entity' with 'Entity.OwnedType#OwnedType', but there is no entity of this type with the same key value that has been marked as 'Added'. Consider using 'DbContextOptionsBuilder.EnableSensitiveDataLogging' to see the key values.'

Steps to reproduce
class Program
{
static void Main(string[] args)
{
var entity = new Entity();
entity.OwnedType.SomeText = "Hello world!";
var context = new TestContext();
context.Database.EnsureCreated();
context.Attach(entity);
context.ChangeTracker.Entries<Entity>().First().State = EntityState.Added;
context.SaveChanges();
context.Database.EnsureDeleted();
}
}
public class Entity
{
public Entity()
{
Id = Guid.NewGuid();
OwnedType = new OwnedType();
}
public Guid Id { get; set; }
public OwnedType OwnedType { get; set; }
}
public class OwnedType
{
public string SomeText { get; set; }
}
public class TestContext : DbContext
{
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)

base.OnConfiguring(optionsBuilder);
}
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
var entity = modelBuilder.Entity<Entity>();
entity.HasKey(e => e.Id);
entity.OwnsOne(e => e.OwnedType);
