Strange rest dots behaviour - bug?

[Thomas Scharkowski]

Hello list,

sorry for the long example, but I could not shorten more.
In bar 9 and 10 of the attached example the rests in voice "Bass" are 
shifted, but the dots remain at the default position.
If I delete or shorten voice "Middle" the problem disappears.


This is a short extract of my code:


\version "2.4.3" % cygwin
\header {title ="Rest dot not shifted"}

Global = {
                \time 6/8
                \clef "G_8"
                \key d \major
                \override Staff.NoteCollision #'merge-differently-headed = ##t
                \override Staff.NoteCollision #'merge-differently-dotted = ##t
                }

Upper = \relative c' \context Voice = "Upper" 
                {
                \Global
                \voiceOne
                s2.*4
                s2.*4

                a,,8 d e g fis b |

                }
                
Bass =          \relative c \context Voice = "Bass"
                {
                \voiceTwo

        }

Middle =        \relative c' \context Voice = "Middle"
                {
                \voiceThree

                }
