"Edit" button appears next to image titles that the user doesn't have permission to edit
Review Request #6747 — Created Jan. 8, 2015 and submitted — Latest diff uploaded
Edit button and functionality was given to everyone as the check was not done on the front end. Checking with the model for ReviewRequestEditor was done to ensure edit permissions were allowed.
Testing was done manually with admin, users (people who created the issue, part of the group/issued to, or not part of the group) and visitors.
