Fix the trivial Bugzilla code request "(Show other bugs)" links to list including all fixed bugs, which is really unhelpful by providing a correct patch in Gerrit which solves the problem. Testing could be done by becoming a group member on Wikimedia Labs(not trivial when it comes to learning), but I hope that it won't be needed for this two-liner issue. :)

Students are required to read Wikimedia's general instructions first. It could be helpful if you have used Bugzilla before but it's not a requirement.
