I tried that, but I don't know how to align it like company does.

I admit I was hoping that you as company maintainer/specialist :-) could
provide a small snippet to create a dummy but company-realistic overlay
of, say, two completion "foo" and "bar" in the middle of any buffer.  Or
perhaps explain in layman's terms how company constructs its overlays.

Not asking that you get to the root of the move-to-column problem, which
is clearly a regression (presumably a regression to correct behaviour,
but a regression nonetheless) just help perhaps come up with a simpler
repro to assist Eli in seeing the issue.

But there's no urgency.  This, I understand, is not in Emacs 28 and
there is a workaround in Eglot.
