Hi! I've noticed something very weird with self-service registration flow (for browsers) today. The AJAX API doesn't send any UI nodes for identity traits anymore, but when a form is submitted without these fields, it reports with an error (which is, yeah, expected behavior, and does mean that schema is correct). I thought the problem is in my custom UI, but then noticed exactly the same behavior with Managed UI. Is it a problem with configuration, or a bug with Ory Cloud?
