Strange, because when I replace the above sexp in step 1 by the
following, I see the same problem at step 2:
(let ((buf (get-buffer-create "*test*")))
(with-current-buffer buf
(setq auto-hscroll-mode 'current-line
truncate-lines t
bidi-paragraph-direction 'left-to-right)
(insert "Subject: Re: bug#39280: 27.0.60; wdired-get-filename ignores first argument (this is a test)\n")
(emacs-lisp-mode)
(goto-char (point-min)))
(show-paren-mode)
(switch-to-buffer buf))

I think I've only seen this on the last line in a Gnus summary buffer.
This also holds for the new test case (also in Emacs Lisp mode): after
evaluating the following sexp, I see the problem only on the last line:
(let ((buf (get-buffer-create "*test*")))
(with-current-buffer buf
(setq auto-hscroll-mode 'current-line
truncate-lines t
bidi-paragraph-direction 'left-to-right)
(insert "Subject: Re: bug#39280: 27.0.60; wdired-get-filename ignores first argument (this is a test)\nSubject: Re: bug#39280: 27.0.60; wdired-get-filename ignores first argument (this is a test)\nSubject: Re: bug#39280: 27.0.60; wdired-get-filename ignores first argument (this is a test)\n")
(emacs-lisp-mode)
(goto-char (point-min)))
(show-paren-mode)
(switch-to-buffer buf))
