Starting a Piano Staff with an appoggiatura (acciaccatura)?

[Joern Eichler]

Hi all,

Trying to start a PianoStaff with an appoggiatura or an acciaccatura seems
broken. Try this little thing to see what I mean. (Yes I know that Lied of
Schubert is in a-minor. I made it e-minor just to show what happens to the f-
sharp accidental).

Or is there something wrong with my example code?

Greetings
Joern
