Oh, I totally forgot the problem bacause of having set this hook,
but by removing the hook I confirmed it still exists.  Thank you
for following this up.

I tried this,

--- gnus-art.el~	2018-03-25 21:34:24.056766300 +0000
+++ gnus-art.el	2018-04-12 05:50:51.190490800 +0000

 	    (gnus-configure-windows 'article)

+	      (goto-char (point-min)))
 	    (gnus-run-hooks 'gnus-article-prepare-hook)

and verified it does the trick, too.  The point is that to select
the article window while performing (goto-char (point-min)).
