When assessment due date has passed for Quizzes.Next, there is no indication in the gradebook or SpeedGrader that it is missing. By contrast, a late submission is noted in the grade book. This occurs with both the new and legacy gradebooks, and in both Chrome and FireFox.
Steps to Reproduce:
Create an assessment and provide a due date.
Add questions or leave no question on the assessment.
When the due date passes, "missing" will not appear in the gradebook or in SpeedGrader
