I won't pretend to understand the internal mechanism that decides which
side the notes should go on, but I would have expected the correction to
work as you did with prefer-dotted-right = ##f, which it doesn't. I also
tried the NoteColumn.force-hshift property, which kind of works. The note
would move successfully, but the dot wouldn't go with it. This would also
need to be a local override and unable to control it globally.
What is done is conventional notation, but I'm curious what is driving your
need to move d2. to the left in m.5? If it's for clarity, I wouldn't
recommend it, but maybe you have a different reason.
Sorry I couldn't be more helpful,
Abraham
