- **Comment**:
Some observations:
- This happens for some other spanners as well, _if_ they are bounded by
spacers _not_ at the same moment as the NoteColumns.
- Replacing the spacer with rests work
- It fails for MetronomeMark, but not for RehearsalMark!
Test code:
~~~~
\version "2.19.52"
\paper { indent = 30 }
\markup \rounded-box "Test with spacers: \\markLengthOn fails"
$@(map
(lambda (mus mrkp)
#{
\new Staff \with { instrumentName = #mrkp }
<<
{ \markLengthOn \tempo "MetronomeMark" c''1 \tempo "next one" d''1 }
{ s4 #mus s1 }
>>
#})
(list
#{ s2\< s4\! #}
#{ s2\startTextSpan s4\stopTextSpan #}
#{ s2\startTrillSpan s4\stopTrillSpan #}
#{ s2( s4) #}
#{ s2~ s4 #}
#{ \[s2 s4\] #})
'("Hairpin" "TextSpanner" "TrillSpanner" "Slur" "Tie" "LigatureBracket"))
\markup \rounded-box "Same with (omitted) Rests: \\markLengthOn works"
$@(map
