Problem: When grading drag-and-drop onto text questions manually student answers are not displayed. For the first student on the page answers are displayed but they change every second at random which is quite distracting. For all following students no answers are shown.

Expected behaviour: Student answers are displayed (and do not change at random) when grading drag-and-drop onto text questions manually.

Quick way to reproduce this: log in as teacher at https://qa.moodle.net/ then go to https://qa.moodle.net/mod/quiz/report.php?id=31&mode=grading&slot=4&qid=52&grade=autograded&includeauto=1 and scroll down. The changes in Moodle 3.6 did not fix this.
