BarNumber vertical positioning won't stay fixed relative to Staff/system

[Kieren MacMillan]

Hello all!

I seem unable to fix the BarNumber vertical positioning relative to the Staff 
it sits above: the BarNumber moves vertically according (it appears) to the 
content of the entire system, not just (as desired) to avoid colliding with the 
StaffSymbol and/or Clef.

This may be related to the fact that I have a ScoreMarks (a.k.a. MarkLine) 
context at the top of my score:

  <<
    \new ScoreMarks \global
    \new Staff << \global \someMusic >>
    ….
  >>

But I can’t guarantee that’s the problem, nor can I put together a particularly 
“minimal” example which shows the problem. Short of sending my current score 
(and all its dependent files) — which demonstrates the problem quite well (see 
the page 1 PDF, attached) — can anyone divine what might be the problem, and 
how to fix it?

Many thanks,
Kieren.

p.s. My intuition suggests this is ultimately related to Issue #2313 
(<https://code.google.com/p/lilypond/issues/detail?id=2313>), since it has to 
do with BarNumber positioning relative to other grobs in the Staff/system… but 
it may be completely unrelated.
