Very cool. In that case, let's consider this issue resolved.
I've already pushed this fix and cut a new release now.
(If you think posn-at-point takes that information from what is
displayed on the glass, or from some of its internal representation,
then that's not what it does, because the internal representation of
what's on the glass is many times outdated when a Lisp program runs,
so it cannot be trusted.)
I was thinking there was some change canary (or many of them), and the
"internal representation" is recomputed when any of those values change.
