由于支付宝不属于默认的类别，所以使用自建方式进行关联注册：
leanUser.logIn(authData: aliAuthData(aliAuth),
platform: .custom("alipay")) { (result) in }
但是当我使用支付宝注册了账号后，再用微信进行注册，并绑定同一个支付宝时，却可以无障碍的绑定成功。
然后我再次使用Apple注册后，尝试绑定同一个支付宝，还是绑定成功。
但是Apple和微信就会返回137错误提示已经存在该账户，并返回相关信息。
请问是我使用的方式不对还是存在bug？
附录：由于不确定是否字段错误造成，同时使用了openid和uid进行标注，以下是三个账户的第三方登录信息：
