I've noticed that =org-get-outline-path= report incorrect information
when =org-element-use-cache= is =t=. This mail shows some experiments
that demonstrates this bug.
* Experiment 1
In this experiment, we define a =func= which contains the sexps that
we want to run when =org-element-use-cache= is =t= and when it is
=nil=. In =func=, we use =org-map-entries= to loop through headlines
that have depth 2. In each headline, we move the point two lines below
and insert a new line containing =FOO=.
#+HEADER: :results output
#+begin_src elisp
(let ((func (lambda ()
(with-temp-buffer
(org-mode)
(insert "* 1
,** 1-1
a
,** 1-2
a
,* 2
,** 2-1
b
,** 2-2
b
")
(princ (format "--- before\n%s\n--- before\n"
(buffer-substring-no-properti
es
(point-min) (point-max))))
(org-map-entries
(lambda ()
;; We get the outline path before calling
;; (forward-line 2) to ensure that we are referring
;; to the headline in the current iteration
(princ (format "org-get-outline-path: %s\n"
(org-get-outline-path t)))
;; Move two lines below the current headline A. After
;; executing (forward-line 2), the point is where
;; the next headline B starts.
(forward-line 2)
;; We add a line which moves the headline B, one
;; line below
(insert "FOO" "\n"))
"LEVEL=2")
(princ (format "--- after \n%s\n---after\n"
(buffer-substring-no-properti
es
(point-min) (point-max))))))))
(princ "Experiment 1.1 (org-element-use-cache nil)\n")
(let ((org-element-use-cache nil))
(funcall func))
(princ "Experiment 1.2 (org-element-use-cache t)\n")
(let ((org-element-use-cache t))

In the results above, we can see that in =Experiment 1.2=,
=org-get-outline-path= returns wrong information (note that the
results are lists of length 3), while in =Experiment 1.1= this doesn't
happen.
* Experiment 2
I noticed that when we pass one paameter (i.e. ="FOO\n"=) instead of
two as we did in the previous experiment (i.e. ="FOO" "\n"=) to
=insert=, the bug doesn't happen. See minimal reproducible example
below.
In this group of experiments we pass ="FOO\n"= instead of ="FOO" "\n"=
to =insert=.

In the results above, we can see that both Experiment 2.1 and
Experiment 2.2 have the same output.
* Personal thoughts
With regards to experiment 2, we know that passing either ="FOO\n"= or
="FOO" "\n"= insert the same content, so I'm wondering how come
passing different parameters to =insert= which result in the same
outcome can affect the behavior of =org-get-outline-path=.

Thanks for reporting!
It was a bug in parser cache code.
Fixed, on bugfix.

The difference is that "FOO\n" is processed a single buffer
modification (insert a string), while "FOO" "\n" triggers two
modifications (insert string, insert another string). The latter case
was not processed properly, missing that "\n" created a new heading:
1. Insert "FOO" ->
FOO** 1-2
2. Insert "\n" ->
FOO
** 1-2

For those interested: here's another minimal working example:
#+HEADER: :results output
#+begin_src elisp
(with-temp-buffer
(org-mode)
(insert "* 1
,** 1.1
,* 2
")
;; jump to the first headline to print the value of :end
(goto-char (point-min))
(princ (format "%s\n" (org-element-property :end (org-element-context))))
;; search
(search-forward "* 2")
(beginning-of-line)
(insert "a" "\n")
;; jump to the first headline to print the value of :end
(goto-char (point-min))
(princ (format "%s\n" (org-element-property :end (org-element-context)))))
