Key Signature Bug in 2.24.0

[nitram45]

Hi all,

I just discovered this huge bug in the recent release of 2.24.0 which
wasn't in the previous version. Placement of key signatures on multiple
staves with transposed instrument behaves very poorly. Consider this
example :

\version "2.24.0"

music = \relative c' {
  \key es\major
  c d e f
  \key c\major
  c d e f
  \key as\major
  c d e f
  \key bes\major
  c d e f
}

\new StaffGroup <<
  \transpose c a {
    \music
  }
  \new Staff
  \transpose c g {
    \music
  }
  \new Staff
    \music
>>
