I'd push back on considering this a bug.
Babel currently makes no guarantees about the location in which
evaluation takes place (other than the :dir header argument), and I
would consider it an implementation detail that evaluation of emacs-lisp
does sometimes take place inside the Org-mode buffer (this is not true,
nor could it be for any other language). By contrast Babel *does*
guarantee that header arguments are resolved in the original Org-mode
buffer, a guarantee that we explicitly maintain during export despite
the Org-mode buffer shuffling.
