staccato oddity

Hey, y'all --

Just found a weird thing here, and I think it's related to my use of 
cross-staff + \voiceOne + \oneVoice: seems that somewhere in the 
flipping back and forth, the Script gets stuck on top (q.v., m10 
staccato).

Could someone please confirm what my problem is?  ;-)

Thanks,
Kieren.
