rightHandFinger#3 positioning (version "2.17.21")

I'm not top posting.

Dear bug-squad, Cher Eluze,

When "strokeFingerOrientations" is set to "up", "rightHandFinger#3" does
not accept false setting to "add-stem-support" (I'm not sure this is well
explained...)

Here's my tiny example :

\version "2.17.21"

rp = -\rightHandFinger #1
ri = -\rightHandFinger #2
rm = -\rightHandFinger #3
ra = -\rightHandFinger #4

Soprano = \relative c''
{
   \stemUp
   \set strokeFingerOrientations = #'(up)
   \override StrokeFinger.add-stem-support = ##t
   c\ri d\rm e\ra f\ri
   \override StrokeFinger.add-stem-support = ##f
   g\rm a\ra b\ri c\rm
}

Bass = \relative c'
{
   \stemDown
   \set strokeFingerOrientations = #'(down)
   \override StrokeFinger.add-stem-support = ##t
   c\rp d\rp e\rp f\rp
   \override StrokeFinger.add-stem-support = ##f
   g\rp a\rp b\rp c\rp
}

\score {
   \new Staff = "Music" <<
      \new Voice = "Soprano" { \voiceOne << \Soprano >> }
      \new Voice = "Soprano" { \voiceOne << \Bass >> }
   >>
   \layout { }
}

Picture's joint.
Thanks in advance.
Pierre
