I tried this for RehearsalMark:

    ;; It's not clear whether having a pure version of
    ;; self-alignment-X is necessary or beneficial.
    (self-alignment-X . ,(ly:make-unpure-pure-container

break-alignable-interface::self-alignment-opposite-of-anchor
                        CENTER))

It made no difference in the regression tests.  What are your
opinions on adding this to the patch?  Does it increase or
decrease your level of comfort?
