Thanks, I merged that one and it indeed fixes the all test failures
on Emacs28.

I still have two new test failures on latest Emacs and I suspect
it's something to do with overlay changes.

Stefan Monnier can you have a look maybe?  Could be related to your
overlay changes?

With Emacs 28 this passes:

   emacs -Q --batch -L . -l yasnippet-tests.el --eval
'(ert-run-tests-batch-and-exit "issue-824")'

With latest master it doesn't.  The issue seems to be a call to
yas-active-snippets which calls overlays-in in where BEG and END
are 1 and which returns no overlays because they have mysteriously
evaporated.  But there are no overlays with 'evaporate' properties
that I can detect.

João
