Using "\set associatedVoice" in deferrely created contexts

[Павел Буданов]

Hi, I want to automatically align syllables in deferrely created lyrics context. Why the following example doesn't work?

<<
   \new Staff \new Voice = "voice" { b b b b b b b b b b b b }
   \new Lyrics {
      s1
      \new Lyrics \lyricmode { \set associatedVoice = #"voice" la la la la }
   }
>>

But if you remove the pause, it will work. When using lyricsto, this also works:

<<
   \new Staff \new Voice = "voice" { b b b b b b b b b b b b }
   \new Lyrics {
      s1
      \new Lyrics \lyricsto "voice" { la la la la }
   }
