Looking into the source code, the culprit appears to be the call to
org-show-all inside org-archive-subtree. The call to org-show-all on
master calls org-cycle-hide-drawers, which goes through every single
drawer (= every archived heading in archive file) and folds it manually
(just to unfold it later). Do not ask.

The code from my config takes care about this. v A will work. I plan to
suggest it for master in future, but I am focused on the org-fold branch
for now. If you wish, feel free to propose a patch based on this code.

Upon reviewing the source of org-archive-subtree, this should not be
needed. Actually, org-mode already disables startup visibility and
various hooks when opening archives. As you can see, it is not
sufficient, since org-archive shoots its own leg later by changing
visibility every time you archive a subtree.

This is odd. All I can suggest then is cloning the repo and searching
using Emacs. Emacs is more reliable when opening org files ;)
