(Sorry, for posting a unfinished (hardly started) reply, some bad
keypress).
I have done more experimentation and the anomaly arises with plain
dynamics (using the extreme pianissisimo to illustrate):
%%%%%%%%%%%%
\version "2.24"
MI = {
c''4 \ppppp
b' %replacing this note with c'' restores the normal note spacing
b' b'
}
MII = {
b'4 b' b' b'
}
\score {
\new StaffGroup %commentating out this StaffGroup restores the normal
note spacing
<<
\new Staff \MI
\new Staff \MII
>>
}
%%%%%%%%%%%%%%%%%%%%%%%%%%
what can the StaffGroup have to do with it?
