Nested scrolling within a stimulus question is asking for trouble as students don't realize that they need to scroll down on the inner scroll bar. This is also made worse by mouse placement when using a scroll wheel on the mouse. I created the below video in our beta environment to see the issue in action.

Whether the stimulus is set to the right or set below, the nested scroll bar is there.

Students feel a unique sense of pressure already when taking an exam and to have a labyrinth of scrolling, panning, clicking, and viewing is insane.

In my opinion, this is a major step BACKWARDS from the classic quizzes and if we get forced into this, we may have to look for another LTI for our quizzes/exams.
