The reproduce steps: With a test org file:
#+begin_src org
#+TITLE: this is title
|
* headline 1
#+end_src
The "|" represent the point, when you put point before the first
heading, the evaluate the bellowing code:
╭────
│ (org-display-outline-path nil t " 〉 " t)
╰────
You will got error:
╭────
│ Debugger entered--Lisp error: (user-error "Before first headline at position
21 in buffer Code Tasks.org")
│ user-error("Before first headline at position %d in buffer %s" 21 #<buffer
Code Tasks.org>)
│ org-back-to-heading(t)
│ org-display-outline-path(nil t " 〉 " t)
│ eval((org-display-outline-path nil t " 〉 " t) t)
│ #f(compiled-function () #<bytecode 0x134accd5971ee056>)()
│ #f(compiled-function () #<bytecode -0x5db3e1955cb81d1>)()
│ eval-expression((org-display-outline-path nil t " 〉 " t) nil nil 127)
│ funcall-interactively(eval-expression (org-display-outline-path nil t " 〉 "
t) nil nil 127)
│ command-execute(eval-expression)

Even I use `ignore-errors` and `with-denoted-errors`, the upper error
still caused the header-line disappeared sometimes.
