Chord fingering bug?

[Nick Payne]

Is this a bug or a known problem or how things are supposed to work? If 
the fingering for the C# is to the left, then the fingering for the A 
automatically avoids the accidental. if the fingering for the C# is 
above the note, whether placed by using ^ or with a \set command, then 
the fingering for the A collides with the accidental.

\version "2.13.30"

\relative c'' {
    \override Fingering #'staff-padding = #'()
    \override Fingering #'add-stem-support = ##f
    \set fingeringOrientations = #'(left)
<cis-4 a-3>1
<cis^4 a-3>
    \set fingeringOrientations = #'(up left) <cis-4 a-3>
}
