      This is a bug discovered on MDL-65252 but will only be patched there for master and 3.11. This issue is about backporting the bug fix.

      test_mod_forum_get_discussion_rating_information  (renamed in the linked issue, so won't exist in stables just yet) should work with the new API method get_discussion_posts(), but results in an unexpected debugging call when fetching the posts as a teacher using this. It used to work with get_forum_discussion_posts() but that's just been finally deprecated (or is about to be).

      This seems to be caused by a bad returnurl on the rating, which means execution falls through and tries to use the $PAGE var, which isn't set up properly, hence debugging is called.

      At present, we're commenting out that test chunk. If you uncomment it, you'll see:

      Unexpected debugging() call detected.
