Staccato alignment on stem side

[Urs Liska]

The following example shows that staccato points are aligned differently 
from other articulations when on the stem side. It is especially 
visible/ugly when in parentheses (and this is how I noticed in the first 
place).

Is this intended behaviour (if yes, why)?
Or is this a bug?
I only found this somewhat related issue: 
http://code.google.com/p/lilypond/issues/detail?id=218
But my point is that the staccato gets aligned differently from the rest.


\relative e'' {
  e-. -| -- e-\parenthesize -. -|--
  \voiceTwo
  e-. -| -- e-\parenthesize -. -|--
}
