‘frameset—mini` as its car, hasmini1/2 are always set to this symbol. The

    JD>           ((eq id-def2 t) nil)
    JD>           ((not (eq hasmini1 hasmini2)) (eq hasmini1 t))

    JD>           (t t))))

    JD> but the 3rd and 4th conditions are never met.  This may cause confusion 
for anyone trying to use the ‘frameset—mini frame parameter.

I guess youʼre looking in emacs-26? In emacs-27 'cdr' is applied to
the 'assq' result.
