I don't get the problem. The following works imho

\new StaffGroup
<<
  \new Staff {
       \grace { \bar "" gis''8 \bar "|" } c''1
       \grace { \bar "" gis''8 \bar "|" } c''1
       \grace { \bar "" gis''8 \bar "|" } c''1
  }
  \new Staff { c'1~ 1~ 1 }
>>

Obviously I'm missing something...

Well, issue 34 is located deep, deep in LilyPond's heart and brain.
Up to now, nobody found a convincing fix.

Nevertheless, you may follow the link I gave here
https://gitlab.com/lilypond/lilypond/-/issues/34#note_339729636
and try it out. (Although it's limited to where issue 34 concerns repeats)

Cheers,
