I am complaining about how org-element.el behaves.

This [cite:@adler_how_1972] becomes this:

(citation
 (:key
  #("adler" 0 5
    (keymap
     (keymap
      (follow-link . mouse-face)
      (mouse-3 . org-find-file-at-mouse)
      (mouse-2 . org-open-at-mouse))
     face org-link mouse-face highlight htmlize-link
     (:uri "cite:@adler_how_1972")
     fontified t))
  :parentheticalp nil :begin 192 :post-blank 0 :end 214 :suffix
  (#4=(underline
       (:begin 204 :end 209 :contents-begin 205 :contents-end 208
:post-blank 0 :parent #3#)
       #("how" 0 3
	 (:parent #4#)))
      #("1972" 0 4
	(:parent #3#)))
  :parent #5#))
