Not exactly sure about the reason why your code fails, though you can
workaround with:

"\\[" =
#(define-music-function (parser location note) (ly:music?)
#{
  #(make-span-event 'LigatureEvent START)
  $note
  \melisma
#} )

"\\]" = { \] \melismaEnd }

\score {
  \new Staff { \[ c1 d \] e }
  \addlyrics { vi -- de }
}


HTH,
