I already did, and I do see the behavior described in the OP. I'm
guessing you will see it as well if you play a little with the font
size.
I will look into this when I have time. It isn't a new problem, so
there's no rush. Redisplay's behavior in the presence of tall images
and small windows was always problematic, and the workaround is easy
enough.
