bug#57972: 29.0.50; Autoloaded function raises (void-function org-element-cache-reset) when called within major-mode body

[Ihor Radchenko <yantar92@gmail.com>]

Hi,

I am forwarding a bug report from Org mode.
https://list.orgmode.org/4a9d4298-4af6-3e11-63c3-87bf7125f61b@oracle.com/T/#u

I am able to reproduce the reported steps (see below) and I find that
the void-function error is raised when calling (org-mode). `org-mode'
body calls `org-element-cache-reset', which should be autoloaded from
org-element.el. Yet, void-function error is raised.

I either misunderstand something about autoload or it is some kind of
Emacs bug.

Steps to reproduce:

Org mode version is the latest from
https://git.savannah.gnu.org/cgit/emacs/org-mode.git/
