Create a course with 'Group mode' set to 'Visible groups'. Enrol two students (A and B) in the course. Add two groups to the course - make sure each group has a lengthy description. Add student A to one group and student B to another. Visit the 'Participants' page. In the 'Visible groups' select box change to one of the groups. Confirm that the group div (see screenshot with the group 'C101' and description 'C101' with an image of a cat) is not displayed on the page. Select 'Student' in the 'Current role' select box and confirm the table heading reads "Users with the role "X" in the group "Y"".
