Aaron,

Thank you so much for this fix and for entering an issue!  There is just
one thing that is a problem for me.  Your solution requires version 2.22
and I'm using 2.24 (with the \alternative command so it's not easy to
change).  When I your solution convert to 2.24 (no changes) I get an error
executing the file:

/home/foo/bar/chords-bar-line.ly:7:9 <0>: error: Guile signaled an error
for the expression beginning here

#

ly:separation-item::print

Unbound variable: ly:separation-item::print
