I closed this one.  Merging them is too much of a hassle with
debbugs's unhelpful defaults for archived bugs.

The only other thing I could say, which may or may not be helpful for
your use case, is that Lisp programs shouldn't assume they will always
find point outside of invisible portion of the text, and instead
actively look for the first visible position after point.
