Hi,

libxml2 has been updated to upstream 2.12.7 release and the
autopkgtest shows regressions[1] regarding ruby-libxml:

Upstream has fixed a few issues with libxml2 2.12.x in 5.0.x release.
It would be nice if upstream release or some patch works can be
considered to help unblock the migration of new libxml2. I would give
it a try on patching but I'm unfortunately not a Ruby expert.
