Start emacs with emacs -Q and paste the following text in the scratch buffer

;;;; Start copy ;;;;
(defun test (nil)
  (test1
    (test2
    "") "***"))
;;;; End copy ;;;;

You will see that the last 7 characters of the last line, i.e., "***")) are
shown with the wrong face. If you insert a new line before those
characters, the correct face is shown.

It's a feature, not a bug.  Move your mouse pointer so it's over the
text displayed in warning face, and read what the tooltip says to
understand why Emacs does that.
