This is working as intended (i.e. not a bug). Lisp-mode explicitly tests
for this. When you hover over the highlighted part, you get a tooltip
"Hidden behind deeper element; move to another line?"
While not a syntax error, there's such a strong convention to avoid such
formatting that the Lisp modes warn unconditionally about it.
