When a user with a teacher role attempts to configure blocks inside a Choice activity, the error "This block (id=X) does not exist on this page" is displayed.
Steps to reproduce:
1. Create a course and a Choice activity.
2. Enroll a user as a teacher in the course and login as that teacher
3. Turn editing on.
4. Click on the activity.
5. Click the "Configure" icon of any block on the page.
6. Save changes (you don't have to actually make any changes).
An error similiar to "This block (id=4) does not exist on this page (http://(Moodle site)/mod/choice/view.php?id=1835)." will appear.
Debug output:
