Hi Federico,

it's because grace-notes are beamed per default with 2.17.96.
Change the example to
\bendGrace { \preBendRelease c8( \noBeam d)( } c2) r2

or better the definition of 'preBendRelease' to

preBendRelease =
#(define-music-function (parser location note) (ly:music?)
   #{
     \once \override TabVoice.Slur #'stencil = #slur::draw-pre-bend-hold
     \once \override TabStaff.ParenthesesItem #'transparent = ##t
     \once \override Voice.Slur #'direction = #DOWN
     \autoBeamOff \parenthesize $note \autoBeamOn
   #})


Sorry for the late reply
