This isn't a bug: cross-staff arpeggios belong to a different context. In
your case, they are a part of PianoStaff, so the override will have no
impact. If you do this, it will work:
offsetCrossStaffArpeggioPositions =
#(define-music-function (parser location offsets) (pair?)
#{
\override PianoStaff.Arpeggio #'positions = #(lambda (grob)
(let* ((func (assoc-get 'positions (cdr (ly:grob-basic-properties
grob))))
(pos (func grob)))
(coord-translate pos offsets)))
#})
OK, that name is out of control :)
HTH,
David
