stanza alignment

[Malte Meyn]

Hi list,

when I have multiple verses the stanza numbers are aligned. This works 
also I put some verses above the a staff and some below. But it doesn’t 
work anymore if I then add another staff. Any ideas how to solve this 
problem? Is this a bug?

Cheers,
Malte

  % uncommenting the following line will break (?) the stanza alignment
  %\new Staff { b b b b }
  \lyrics {
    \set stanza = "3." a a a a
  }
  \new Staff { b b b b }
  \lyrics {
    \set stanza = "1." aaaaaaaaaaaaaaaaaaaaaaaaaa a a a
  }
  \lyrics {
    \set stanza = "2." a a a a
