Maybe, this is a bug. I noticed in scm/define-grobs.scm that the
property break-align-symbol of the RehearsalMark object is set to
time-signature. However, the break-aligned-interface is not included
among the interfaces of the object.
I tried to add the interface and to set the property to different
values, but didn't notice any difference. I'm not sure how these
things are supposed to work but it should at least be a bug to
set a property that's not included among the interfaces of the
object (which also means that it's not included in the documentation).
