In a course, create a glossary with the option Allow comments on entries enabled. Add two glossary entries, then view the index of the glossary with all entries shown. Each entry should have its own comment area underneath it. Add a comment to one of the entries. You should see an animation as the comment fades in. Verify that the count of comments on that entry has changed accordingly. Delete the comment. You see an animation where the comment disappears. Verify that the count of comments on that entry has changed accordingly. Add two comments to the entry you didn't add comments to, as well as one comment on the entry you did. Verify that the comment counts are changing properly. Refresh the page. Verify that the comment counts are still correct.
