If my parent slide is longer than a single slide, when I navigate from an overlay slide back to the parent slide, it jumps all the way to the top of the slide. This causes frustration as the learner now has to scroll all the way to where they left off just to continue the content.
On the other hand, when navigating from one slide to the next slide, the next slide opens at the bottom of the slide.

For slide-to-slide navigation, it should always start at the top and for overlay-to-parent it should resume where the learner left off.
