Hi Johannes,
this is a known issue that beats Lilypond users since
a long time and unfortunately very hard to fix:
https://gitlab.com/lilypond/lilypond/-/work_items/34
https://lilypond.org/doc/v2.25/Documentation/notation/special-rhythmic-concerns.html#grace-notes
TLDR;
insert an invisible grace note at
the beginning of
`PianoLHMusic`.
