Yes.  Well, the bad news is that the kind of inline LaTeX hacking you
did (for 1.2), is not and has never been a recommended or supported
feature.  LilyPond cannot calculate the dimensions of such a hack.
(La)TeX hacking should only be used if there's really no other option
(chinese lyrics come to mind).

You can use boxed molecules, like so:

    \score{
        \notes \relative c''{

            \property Score.RehearsalMark \override #'molecule-callback =
            #(make-molecule-boxer 0.15 0.3 0.3 Text_item::brew_molecule)

            a \mark "A"  b c \mark\default d
        }
        \paper{
             indent = 0.0\mm
             linewidth = 50.0\mm
         }
    }

Circled molecules have not been implemented yet.
