I embedded few Engage and Quizmaker slides in Presenter 360, Published as HTML5 output with settings restricted(linear) navigating and SCORM 2004 3rd edition. When I resumed it doesn't retain viewed status for Engage and Quizmaker slide titles in menu. However I can complete the course successfully. The problem is only with menu status. Engage file properties in order are "Single Item", "At any time" and "Step in the interaction".
