It seems to me that you’re trying to solve a problem that I, who engraves music
as a big part of my living, never try to solve: you’re trying to feed the
current placement of an object back into the spacing engine in order to
recalculate and redraw the layout. (I assume this is because you’re trying to
code/improve your JS UI for editing Lilypond files?)
As an engraver, I simply look at the generated score, manually adjust the
padding or Y-offset or extra-offset [as makes the most sense], and recompile —
it’s not particularly tedious, and is far more accurate (at least at this stage
of "artificial intelligence") than trying to get Lilypond to calculate it (even
with multiple passes).

Hmmm… I don’t think that’s true. Any object whose reference point is calculated
relative to the staff behaves the same way, right?

I haven’t read the whole thread, but did you suggest an implementable mechanism
which would fix this "bug" for you?
One hack would simply be to increase the Y-extent by the amount of extra
"offset" you want; probably you’ll have to use unpure-pure containers.
Hope that helps!
Kieren.
