This is a major issue when performing usability tests because there is no visual cue that the screen mockup extends past viewport height. We added our own scrollbars to the mockups but now people try to click on them, which is at least better than no scrollbar because it at least helps us to know that users expected to see more below the viewport height when they saw a scrollbar.
