[2.14.2] cadenzaOn makes [ ] behave like ( ) with regards to lyrics (regression vs 2.12)

[Frédéric Bron]

In the following code, no word is placed below the second eight note.
Commenting \cadenzaOn or removing manual beaming [] works fine.
Manual beaming [ ] behaves like slur ( ).
This worked in previous versions.

\version "2.14.0"
\score {
   <<
      \context Voice = "notes" \relative {
         \cadenzaOn
         c1 c8[ c8] c2. \bar "|" \break
         \cadenzaOff
      }
      \lyricsto "notes" \new Lyrics { one two three four }
   >>
}
