\articulate works wrong with repeat volta alternative
\version "2.23.5"
\layout { \context { \Staff instrumentName = #(lilypond-version) } }
mus.old-syntax = \repeat volta 2 { bes1 } \alternative { b! bis }
mus.new-syntax = \repeat volta 2 { bes1 \alternative { b! bis } }
\include "articulate.ly"
\articulate \unfoldRepeats \mus.old-syntax
\articulate \unfoldRepeats \mus.new-syntax
The newer syntax it is not unfolded correctly, both alternatives are printed.
While deleting \articulate
it works correctly.
2.23.5 also prints superflous volta brackets, this is already fixed in master, thus I attach the 2.23.6 output.
