When a question issue is reported by a site admin, a teacher cannot list issues for this question: frame loads indefinitely

as in the title.

Tried to reproduce this, but it seemed to be working now. Tested on Moodle 4.1 with Safari and Google Chrome.

Steps:

1. Created two question issues for a test question as admin user.
2. Switched to teacher user.
3. Attempt listing all issues for the question.
