MapIdentityApi email confirmation links uses relative instead of absolute URLs #50296
Description
When you register a user with MapIdentityApi's /register endpoint, it sends an email with a relative confirmation link like /identity/confirmEmail?userId={id}&code={code} rather than https://example.com/identity/confirmEmail?userId={id}&code={code} which makes the confirmation link unusable.
