Hello

I've come across what seems to be a bug in org-element-cache handling.

To reproduce:
1) create a level 1 heading (in my case: "CAPTURE") and a level 2 heading
(in my case: "CAPTURE-TEST")
2) create a similar template to file tasks under a level-2 heading:
("x" "Todo (test)" entry
(file+olp "~/Workcloud/org/WORK.org" "CAPTURE" "CAPTURE-TEST")
"* TODO %^{Task Description}"
:prepend t)
3) create a task using this template (x)
4) while in the narrowed buffer, try to tag the task using C-c C-q
(org-set-tags-command)

This will hang. Pressing C-g helps you recover, the stack trace being
Debugger entered--Lisp error: (quit)
  #f(compiled-function () #<bytecode 0x1321472668e93f>)()
  org-element--parse-to(77445)
  org-element-cache-map(#f(compiled-function (el) #<bytecode
0x184aaa442bea9805>))
  org-get-buffer-tags()
  org-set-tags-command(nil)
  funcall-interactively(org-set-tags-command nil)
  call-interactively(org-set-tags-command nil nil)
  command-execute(org-set-tags-command)

Disabling the cache with (setq org-element-use-cache nil) solves the
problem.
As does dropping "CAPTURE-TEST" in the template (i.e. putting the task
under a level-1 heading instead of level-2).
