注册时，如果省略必填的自定义用户字段，则不显示错误提示

Instead of showing an error hint, like it’s done for standard fields, the custom user field shows no message if omitted. Signup just does nothing without any feedback to the user.

We have reproduced this issue and are our team our now investigating.

Thank you for bringing this to our attention!
