Could you please provide a detailed recipe, starting with "emacs -Q",
for reproducing the problem?  I cannot reproduce this on my system,
but I'm not sure I understood the procedure (e.g., what are "vertical
split" and "vertical border"?).

Also, you are using a very old snapshot of the development sources;
could you update to the latest code and see if the problem is still
there?

Thanks.
