Strangely, this doesn't seem to happen with every image. "splash.png" in
the Emacs repository seems fine, for example. I also can't reproduce
this in EWW, even by opening the bad image reported in this bug.
I haven't looked into the internals of 'image-mode' very much, but I
seem to recall that it has some special code for scrolling large images.
Maybe that's interacting in some bad way with 'visual-wrap-prefix-mode'?
One option might simply be to disable 'visual-wrap-prefix-mode' when in
'image-mode'. I don't think wrapping is useful in that context.
