Did you try my fix, to move the Break_align_engraver to the Staff context?
\layout {
\context {
\Staff
\consists "Mark_engraver"
\consists "Break_align_engraver"
}
\context { \Score
\remove "Mark_engraver"
\remove "Break_align_engraver"
}
}
I have tried it on a couple of examples and cannot see that it
introduces any
other problems.
