Killed staves affect vertical spacing

[Xavier Scheuer]

Hi,

OK, this may be related to issue #1309 or more probably to #127 .
This is not a regression from 2.12.3.

%% I would have expected the second "ossia" to be right under the
%% normal staff.  Instead it is shifted below, like if the "killed"
%% ossia staff was still there (invisible).

\version "2.13.39"  % it's the same with 2.12.3

\score {
 <<
  \new Staff {
    \relative c'' {
      a4 a a a
      <<
        { a4 a a a }
        \new Staff { b4 b b b }  % first ossia
      >>
      a4 a a a
      <<
        { a4 a a a }
        \new Staff { b4 b b b }  % second ossia
      >>
    }
  }
 >>
}


Cheers,
Xavier
