suggestAccidental symbol too big in 2.10

[Robert Memering]

Hi all,

in the current stable branch the small accidental
symbols produced with suggestAccidentals = ##t are
not scaled when the Staff is scaled using the method
shown in the example below.

This issue is fixed in 2.11, but at the moment I can't
use 2.11 because it completely breaks the carefully
balanced (fixed) vertical spacing of my A3 40-voice score.

Is there any chance that this bug gets fixed in 2.10 ?
I would really love to publish my edition in "1.0-quality".

Regards,
Robert


EXAMPLE:

\version "2.10.19"
\include "deutsch.ly"

\new Staff = "foobarbaz" \with {
  fontSize = #-3
  \override StaffSymbol #'staff-space = #(magstep -3)
}
{\set suggestAccidentals = ##t cis''}
