Since this patch aims to fix pagelayout-report in ../mod/quiz/report.php?id.. the tester needs to have a quiz which has been attempted by a student or students the more the merrier. Although I actually tested this with only one student who had made 2 attempts at one question, but there was sufficient info to scroll the page if the browser window was resized.(see screen-shot) Login as Admin select Sky High theme in normal way. Go to a Quiz page and in the Navigation block select Quiz/Results/Grade Test that the table container scrolls horizontally.
