removing Stem_engraver blows up polyphony

[Trevor Bača]

Hi,

This snippet with the Stem_engraver removed works fine.

%%% OK %%%

\version "2.9.13"

\new Staff {
  <<
     \new Voice \with {
        \remove Stem_engraver
     } {
        b'4
        f'4
        g'4
        c''4
     }
  >>
}

%%% END OK %%%


But this polyphonic snippet (also with the Stem_engraver removed) blows up.

%%% BUG %%%

\version "2.9.13"

\new Staff {
  <<
     \new Voice {
        c'''4
        c'''4
        c'''4
        c'''4
     }
     \new Voice \with {
        \remove Stem_engraver
     } {
        b'4
        f'4
        g'4
        c''4
     }
  >>
}

%%% END BUG %%%


Here's the output.

FWIW, this is *not* an urgent bug for me since I'm comfortable setting
Stem #'transparent = ##t to achieve pretty much the same thing.
