If you sign up with a plus sign in your email, your account can't be used or recovered

I signed up for the username "solidgold" with the email address "jon+solidtest@snap.com" and this caused a situation where I can't log into the account because it thinks my password is wrong (even though my password is correct) and I can't do a password reset because there is an internal error when trying to do the password reset.

通过使用包含加号的地址注册来复现该问题，然后测试该账户的登录和密码恢复。跟踪这些流程中涉及的身份验证和恢复入口。完成标准是，使用 plus 地址的账户能够使用正确的密码登录，并且能够在不发生内部错误的情况下完成密码恢复。
