\arpeggioArrow* across voices

[Patrick Schmidt]

Hi all,

it doesn't seem to be possible to draw arrow-type arpeggios across  
several voices. In the following example the arpeggio is drawn but  
the arrow is missing.

\version "2.13.30"
musicVoiceOne =  {
  \arpeggioArrowUp
  <b e' gis' b' e''>4\arpeggio
}
musicVoiceTwo =  {
  %\arpeggioArrowUp
  e4\arpeggio
}
chordTest =  {
  \arpeggioArrowUp
  <e b e' gis' b' e''>4\arpeggio
}
\score {
  \new Staff \with {
    \consists "Span_arpeggio_engraver"
  }{
    <<
      \set Staff.connectArpeggios = ##t
      \new Voice {
        \voiceOne
        \musicVoiceOne
      }
      \new Voice {
        \voiceTwo
        \musicVoiceTwo
      }
    >>
  }
}
{ \chordTest }

Did I miss something or is this a (known?) bug? Is there a workaround?

Thanks for your help
