This is by design. The gap represents the viewport height. This is important for scenarios where the AnnotatedScrollbar needs to display labels for content that is located somewhere past the point where scrolling ends. As an example, if in your screenshot above, the last 3 rows were Green, the 'Green' label would be displayed in the gap.

I see. But it seems unnatural. I think it would be improved if the thumb had a length like a normal scrollbar.
