Another way to replicate this without having focus following mouse, is
to use ediff, leave the control frame in its default location over the
main frame and where you have two areas of differences close together
and from the second diff you go back to the first (still visible) -
press 'p' , part of the control frame gets moved down the background
frame (Windows 98 SE here in case that's becoming relevant)

In this case the fonts are identical however there are different text
properties operating
