When I tangle code "C-c C-v t" of this org-mode file:

        #+title: Demo
        #+property: header-args:sh :tangle example.sh :comments link

        * Part A
        ** source
        #+begin_src sh
          echo "Part A"
        #+end_src

        * Part B
        ** source
        #+begin_src sh
          echo "Part B"
        #+end_src

I get this example.sh file

        # [[file:poub.org::*source][source:1]]
        echo "Part A"
        # source:1 ends here

        # [[file:poub.org::*source][source:1]]
        echo "Part B"
        # source:1 ends here

Now I move to the line "echo "Part B"" of this example.sh file and call
org-babel-tangle-jump-to-org. This causes me to jump back to the
org-mode file as expected, but it jumps to the "* Part A" heading instead
of the right "* Part B" heading.

If I manually modify the generated example.sh file as follows

        # [[file:poub.org::*source][source:2]]
        echo "Part B"
        # source:2 ends here

then org-babel-tangle-jump-to-org works correctly and jumps back to
right "* Part B" header's source block.

Do you observe the same behavior ? Is there a way to get expected behavior
(still having 2 headings with the same "source" name) ?

Thanks,
despite that, org-mode is awesome! :)
