Vertical aligning of lyric stanzas

[Anna Choma]

Hello,

I have a piece with lyrics made in lilypond 2.6.3. Now I have lilypond
version 2.7.22 (because of piano brace failure in 2.6). The problem
is, that in the newer version minimumVerticalExtend property doesn't
work and I don't know why. Every voice has 2 stanzas. Here is the
source code:

\score {
 \context ChoirStaff <<
  \context Voice =
   discantusNotes <<
   \set Staff.instrument = "Cantus"
   \global \discantusNotes >>
   \lyricsto "discantusNotes" \new Lyrics {
     \set minimumVerticalExtent = #'(1.2 . 2.4)
     \discantusLyrics }
   \lyricsto "discantusNotes" \new Lyrics {
   \set minimumVerticalExtent = #'(-2.0 . 2.2)
   \secondLyrics }
  \context Voice =
   altusNotes <<
   \set Staff.instrument = "Altus"
   \global \altusNotes >>
   \lyricsto "discantusNotes" \new Lyrics {
    \set minimumVerticalExtent = #'(1.2 . 2.4)
    \discantusLyrics }
   \lyricsto "discantusNotes" \new Lyrics {
    \set minimumVerticalExtent = #'(-2.0 . 2.2)
    \secondLyrics }

And so on, there is 4 voices. \set minimumVerticalExtent property
doesn't work. Is there any knew possibility of doing this?

Best regards,
