Scrollbars were never meant to jump instantly anywhere. They are intended for progressive movement in either direction. It's a much more recent feature implemented as "minimap" in several IDEs. The difference is that minimap actually renders preview of the content to jump to, so you don't jump blind. Add: autohide is there because oftentimes it is obvious content can be scrolled by observing it does not fit entirely in the viewbox.
