Hi Nicolas,
Sorry for the delay. I finally had time to improve this fix (my first
fix caused another regression) and add a regression test. At the moment,
I don't have push rights to the Org Mode repo, so I'm attaching the
patch here.
Best,
Matt

Subject: [PATCH] Ensure that org-get-tags returns all local tags
* lisp/org.el: (org-get-tags) Create a clearer separation between
local and inherited tags in the function, so that
org-remove-uninherited tags is only run on inherited tags. This is
important to avoid destroying existing tags when adding new tags.
* testing/lisp/test-org.el: (test-org/get-tags) Add regression test
