无法将实体类型[TType]添加到模型，因为已经存在具有相同名称的弱实体类型

Question

在将ef-core从2.1版升级到2.2版（2.2.2）之后，我在进行迁移时开始出现错误。 我创建了一个测试项目，这是我的代码：

public class Root
    {
        public int Id { get; set; }
        public MainAddress Address1 { get; set; }
        public MainAddress Address2 { get; set; }
    }

public class MainAddress
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public  SubAddress SubAddress { get; set; }
    }

public class SubAddress
{
    public int Id { get; set; }
    public string Name { get; set; }
    public int Number { get; set; }
    public SubSubAddress SubSubAddress { get; set; }
}

public class SubSubAddress
{
    public int Id { get; set; }
    public string Text { get; set; }
}

public class RootConfig : IEntityTypeConfiguration<Root>
    {
        public void Configure(EntityTypeBuilder<Root> builder)
        {
            builder.ToTable("Roots");

            builder.HasKey(it => it.Id);

            builder.OwnsOne(root => root.Address1, address =>
            {
                address.OwnsOne(a => a.SubAddress, subAddress =>
                {
                    subAddress.OwnsOne(it => it.SubSubAddress);
                });
            });

            builder.OwnsOne(root => root.Address2, address =>
            {
                address.OwnsOne(a => a.SubAddress, subAddress =>
                    {
                        subAddress.OwnsOne(it => it.SubSubAddress);
                    });
            });
        }
    }

public class TestContext : DbContext
    {
        public TestContext(DbContextOptions<TestContext> context) : base(context)
        {

        }

        public DbSet<Root> Roots { get; set; }

        protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
            base.OnModelCreating(modelBuilder);
            modelBuilder.ApplyConfiguration(new RootConfig());
        }
    }

因此，当我更新数据库时出现错误： System.InvalidOperationException：无法将实体类型'EFError1.Models.SubAddress'添加到模型中，因为已经存在具有相同名称的弱实体类型。

如果我使用OwnsOne嵌套2次-那么一切都很好。 有想法吗？
