Moving note in three-voice context

[Jakob Pedersen]

    Greetings!
    
    I'm attempting to move a note horizontally to fix a poorly placed
    voice-leading line.
    
    Breitkopf fixes it by nudging the a following the staff change to
    the right, and I'd like to copy that.

    A minimal example from my score:
    
    \version "2.24.1"
      \language "deutsch"
      
      global = {
        \key g \major
        \time 4/4
        \showStaffSwitch 
        \override VoiceFollower.style = #'dashed-line
      }
      
      rightOne = \relative c'' {
        \global \voiceOne h4 h a g | fis!2 f'~ | f4 f e d |
      }
      
      rightTwo = \relative c'' {
        \global \voiceTwo g4 f e2 | \voiceThree d2 d'~ | d h |
      }
      
      leftOne = \relative c' {
        \global \voiceOne e4 d c h |
        a \change Staff = "right" \voiceTwo \once \override
      NoteColumn.force-hshift = #3 a' gis a | h2 e, | 
      
      }
      
      leftTwo = \relative c' {
        \global \voiceTwo e,2 a | d,2. c4 | h2 h' | 
      }
      
      pedal = \relative c {
        \global c1~ | c4 c h a | gis2 gis' | 
      }
      
      \score {
        <<
          \new PianoStaff <<
            \new Staff = "right" << \rightOne \\ \rightTwo
      >>
            \new Staff = "left" { \clef bass << \leftOne \\
      \leftTwo >> }
          >>
          \new Staff = "pedal" 
          << \clef bass \pedal >>
        >>
        \layout { ragged-first = ##f }
      }
    
    I've included a couple of extra bars because I wasn't sure if it was
    related to something in those.
    
    \once \override NoteColumn.force-hshift = #3
    doesn't seem to work.  (3 was just an arbitrary number to see
    if it would move.) I can nudge the notes at the beginning of the bar
    to the left, except the force-hshift fails to work on the tied d in
    the bass line. 
    
    I'm sure there's a simple explanation, but I've been unable to
    figure it out so far.
    
    
    Best wishes,
    
    Jakob Pedersen
    
    
    ps. There's a free imaginary balloon to anyone who
      recognises the piece.
