\StaffGroup \consists "Mark_engraver"

[Pierre-Luc Gauthier]

Hi there,

I'm trying to move the "Mark_engraver" from the \Score context to the
\StaffGroup context so as to have \mark \default be displayed at the
top of every new \StaffGroup.

I'm not sure why this does not work though :

What I get is marks pilled at the top of the score.

\version "2.21.0"

music = \relative c' {
  \mark \default
  c4 d e f g a b c
}

someGroup = \new StaffGroup <<
  \music
  \music
>>

\score {
  <<
    \someGroup
    \someGroup
    \someGroup
  >>
  \layout {
    \context {
      \Score
      \remove "Mark_engraver"
    }
    \context {
      \StaffGroup
      %\Staff
      \consists "Mark_engraver"
    }
  }
}

Thanks for any pointers.
