Glissando no longer printed within graces?

[Xavier Scheuer]

Hi,

Since a few months I am using my own "glissandoGrace" grace-function
to print glissando without starting note (I made this "modified" grace
invisible, but the glissando visible).

Unfortunately I see that with 2.13.61 a glissando within a grace is no
longer printed.

Here is a minimal example, output with 2.12 and 2.13 are in attachment.
Is this intentional?  Or should it be considered as a bug ?

  %% MINIMAL EXAMPLE
  %% glissando-within-grace

  % Just to actually *see* the glissando (minimum-length)
  \once \override Glissando #'springs-and-rods = #ly:spanner::set-spacing-rods
  \once \override Glissando #'minimum-length = #4
  \grace c'8 c''4

  %% END OF MINIMAL EXAMPLE


Cheers,
Xavier

PS: Just as information, here is my "glissandoGrace" grace-function.

startGlissandoGraceMusic = {
  \once \override Glissando #'springs-and-rods = #ly:spanner::set-spacing-rods
  \once \override Glissando #'minimum-length = #4
  \hideNotes
  s1*0\glissando
}
stopGlissandoGraceMusic = {
  \unHideNotes
  s1*0
}
glissandoGrace = #(def-grace-function startGlissandoGraceMusic
stopGlissandoGraceMusic
   (_i "Create an invisible grace for glissando without starting note"))
