I looked and helm-org does include a similar adjustment to make it work
correctly:


https://github.com/emacs-helm/helm-org/blob/b7a18dfc17e8b933956d61d68c435eee03a96c24/helm-org.el#L490-L523

My patch aims to get you completion with the default completion and also
for any framework that complies to it out of the box. Without my patch
(and without helm-org) you don't get completion after the first tag I think.
