A regression may have been introduced since groff 1.23.0 in regards to nested
marked lists, where the list mark for the outer marked lists is overwritten by
the mark of the nested marked list when using groff 1.24.0-rc3:

groff -Tutf8 -P-cbou -mm mwe-ml.mm | cat -s

                            MWE For ML Bullets

       • Bullet

         □ Square

           ○ Circle

             ◊ Lozenge

           ◊ Circle

         ◊ Square

       ◊ Bullet


Groff version 1.23.0 renders the list marks correctly:

groff -Tutf8 -P-cbou -mm mwe-ml.mm | cat -s

                            MWE For ML Bullets

       • Bullet

         □ Square

           ○ Circle

             ◊ Lozenge

           ○ Circle

         □ Square

       • Bullet
