Description

A bug was found in Doorway where one could assign a visible MSQ to a draft listing and then change the status of the MSQ back to draft causing problems for the listing. A check has been added to prevent returning a visible MSQ to draft once it is associated with a listing.

Open question: do we want a better error message for this than the generic one on the FE?
