Ran into something "interesting" while browsing this page:

Notice the scroll bar at the bottom, if one try to scroll towards the right, said scrollbar will continually shrink, so there is no way to scroll all the way to the right.

Tested in microb, and while the bar shows up, it never presents the same behavior (the scrollbar bottoms out as expected from its shape).
