Using a create_customer and customer_login form on the same page

We do need the abilitiy to use both, the create_customer and customer_login form on the same page.

 

When doing so, logging in and creating new accounts works well. However, we do experience some bugs:

User logs in with a wrong password:
The error message appears on both forms. Is there a way to check which form causes the errors?
 
User tries to create an account which already exists
Unfortunately, there is no error message at all. I assume that this happens because the error happens on the second form (register form) and not the first one.

My section code:
 
{{ 'login-register.css' | asset_url | stylesheet_tag }}
