Would it be possible for you to test this in > Emacs 28? 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.
