That's the master branch.  You need to look at emacs-26, which is
where I fixed this.  There's a dialog box on the top right corner of
the window, which should say "master"; click the arrow, and select
"emacs-26".

That the doc string of help-window-setup says something that sheds
light on with-help-window.
