1. emacs -Q

2. {C-x C-f my-file.el RET}

3. write in my-file.el:

  (defun my-function ()
  (message "Hello"))

4. {M-x emacs-lisp-native-compile-and-load RET}

5. {C-h f my-function RET}

6. Then I see:

my-function is a native-compiled Lisp function in
‘~/.emacs.d/eln-cache/29.0.50-44cd31c8/my-file-fb862712-14785989.eln’.

(my-function)

Not documented.

But I am expecting to see link to my-file.el and not to compiled file.

And if I click on the link:

‘~/.emacs.d/eln-cache/29.0.50-44cd31c8/my-file-fb862712-14785989.eln’.

then I get:
