Comment 1 for bug 1703680

Thank you for the report, David. I could replicate it.

Test scenario:

1. Set up 2 users on your Mahara site.
2. As site admin, set up an open group.
3. Go to Administration -> Groups -> Administer groups and click the "Copy group" button 35 times to quickly create groups or create a CSV file and upload a bunch of open groups.
4. Log in as the second user (as the first one will be an admin in all groups if created via the interface).
5. Navigate to the second result page on "Groups" -> "Find groups".
6. Note the name and URL of the open group that you are planning on joining.
7. Click the "Join this group" button.

Expected result: You joined the selected group.
Actual result: You joined the first open group on the first page of the results.
