Enrollment in a course with a full-capacity offering

Hi all,

I have the following scenario:

• A course is active for self-service enrollment and visible to learners.
• There is one offering associated with the course, which is also active and has a maximum capacity of 12 learners (with no waitlist enabled for self-service).

Question:
When the 13th learner accesses the course and clicks "Enroll", are they still enrolled in the course but not in the offering (since no seats are available)?
Or is the expected behavior that no enrollment is generated at all?

In the attachment are the screenshots of the configured settings.

Thank you,

Anamaria
