Perhaps you missed the point: Since the rehearsal mark is typeset at the
score level, it's not tied to any specific stave and can therefore not be
aligned to an anchor point in a single stave. The strategy used in the 
implementation
is to take the average position of the anchor points in all the stave.
The reason that the anchor point was different in the first stave in 
this particular
example was that the bug reporter hadn't realized this fine detail when he
wanted to change the alignment point. So, it's clearly not a bug, but a lack
of documentation.

Don't add a new LSR item for this issue. I have updated the documentation
in GIT, in the example of sect. Text marks, and added a sentence of 
explanation.
