Hmm, again the problem is that the parts after a line break of broken dynamic

ly:grob-extent, which checks for the common refpoint of the spanner and its
parent (which is 0)...
I think you're misreading this. The common refpoint is a System; it
doesn't have a parent since it's the top-level grob. The problem is
that the broken spanner is expecting a different System.
So, I more and more get the impression that the approach of simply killing the
line spanner and letting its child dynamic spanners live on is the wrong
approach to \breakDynamicSpan and spanner's style=#'none...
Yep, it definitely appears to be too naive.
