Apparently, if the field is marked as valid at least once, directus will allows to save the item even if it not valid anymore.

Steps to Reproduce

1. Create a masked field with email template.
2. Create a new field and input a valid email address, example [email protected].
3. Notice that directus allow the item to be saved.
4. Delete last 3 chars so that email is equals to test@email (<- invalid).
5. Directus still allow the item to be saved.
