My original test case should demonstrate this as well, as the buffer
should be scrolled beyond EOB.  Then (previous-line) up until EOB is
back out of view, then scroll back down and the problem should be
visible.  I also recorded a video for illustration in case this is one
of those only-on-my-machine cases (which it might be, as I built off a
merged native-comp branch): https://www.youtube.com/watch?v=EKrbrVGbEZw
