How does this work?
By "fontification inside scrolling" I mean fontification triggered by
calling move_it_* functions, which simulate display. They will only
fontify those parts of text over which they iterate, which might be
much less than the window.

It's hard to say, but I'm almost sure I sometimes indeed see a small
part of the scrolling window, near its beginning, fontified. Or maybe
I'm just imagining things.
