Re: cross staff/voice arpeggio error

I can see that, but how do you accomplish an arpeggio between voices
otherwise? I want to be able to have an arpeggio extend across voices
in different staves and across different voices in the same staff.
This was how I was able to do it in previous versions of lilypond.

If I do '\new Staff \with {\consists "Span_arpeggio_engraver"}' along
with '\set Staff.connectArpeggios = ##t' inside that staff,
cross-voice arpeggios work in that one staff. If I do '\set
PianoStaff.connectArpeggios = ##t' instead I get the error of course.
Is there another option which would allow for both? Thanks again for
looking at this.

\version "2.11.21"
\layout { ragged-right = ##t }

\new PianoStaff <<
\set PianoStaff.connectArpeggios = ##t
\new Staff \with {\consists "Span_arpeggio_engraver"}
\relative c'' {
  \set Staff.connectArpeggios = ##t
  <<
    {
      c1\arpeggio
    }
    \\
    {
      g2\arpeggio a
    }
  >>
}
