Vertical spacing is broken when \change Staff and \showStaffSwitch on \pageBreak

Hi,
here is example of this bug:

\version "2.24.3"

\score {
   <<
     \new StaffGroup
     <<
       \new Staff \relative c''{ \clef treble c1 | \pageBreak c1 }
       \new Staff \relative c'{ \clef treble c1 | c1 }
     >>
     \new StaffGroup
     <<
       \new Staff \relative c'' { \clef treble c1 | c1 }
       \new Staff \relative c' { \clef treble c1 | c1 }
       \new Staff \relative c' { \clef treble c1 | c1 }
       \new Staff \relative c' { \clef alto c1 | c1 }
       \new Staff \relative c' { \clef alto c1 | c1 }
       \new Staff \relative c { \clef bass c1 | c1 }
     >>
     \new StaffGroup
     <<
       \new Staff \relative c'' { \clef treble c1 | c1 }
       \new Staff \relative c' { \clef treble c1 | c1 }
       \new Staff \relative c' { \clef treble c1 | c1 }
       \new Staff \relative c' { \clef alto c1 | c1 }
       \new Staff \relative c' { \clef alto c1 | c1 }
       \new Staff \relative c { \clef bass c1 | c1 }
     >>
     \new PianoStaff
     <<
       \new Staff = "1" <<
         \new Voice \relative c'' { \voiceOne \clef treble c1 | c1 }
         \new Voice\relative e' { \voiceTwo e1 | e1 }
       >> \new Staff = "2" <<
         \new Voice \relative c' { \voiceOne \clef bass c1 | \showStaffSwitch \change Staff = "1" c1 }
         \new Voice \relative c { \voiceTwo c1 | c1}
       >>
     >>

   >>
}



The problem occurs only if the \showStaffSwitch command is found.
