AuditFields作为审计字段被Car继承，此时生成的Car错误

// 错误示例
declare namespace API {
  type AuditFields = {
    lastUpdatedOn?: string;
    createdOn?: string;
  };

  type Car = {
    ""?: AuditFields;
  } & {
    no: string;
    name?: string;
    userInfo?: UserInfo;
  };

  type UserInfo = {
    id?: string;
    name?: string;
  };
}

// 正确示例
declare namespace API {
  type AuditFields = {
    lastUpdatedOn?: string;
    createdOn?: string;
  };

  type Car = AuditFields & {
    no: string;
    name?: string;
    userInfo?: UserInfo;
  };

  type UserInfo = {
    id?: string;
    name?: string;
  };
}
