Now I see that it works with emacs -Q

I cannot know which customization is getting in the way as there are
too many.

Maybe some customization is telling on my side to expand from the
other window, maybe my (setq dired-dwim-target t) as when I put it to
nil, then it is expanding just how I mean it.

So I was ordering Emacs to Do What I Mean... and it did not do what I
mean.

Now you can close it.
