before-title-spacing mess up with automatic page breaks

[Xavier Scheuer]

Hi Joe!

Another bug involving the new vertical spacing system reported on
LilyPond French Users mailing list.

This one is concerning "before-title-spacing", which mess up with
automatic page breaks (systems run off the page).
Could you have a look at this, please?

BTW should I send this to bug-lilypond, at least to keep a track of
this issue (same question for "VerticalAxisGroup #'next-staff-spacing
and \RemoveEmptyStaffContext") or is it unnecessary since you already
take care of this?

Thanks a lot.
Have a nice holiday!

Cheers,
Xavier


%% "before-title-spacing" fails with (automatic) page breaks

%% Without "minimum-distance" before-title-spacing is reduced to 0
