Code Jump only in the same notebook

[on46zohu]

I am not sure if it's a bug or the intended behavior, (could not confirm in the documentation), but I have the following issue:

If I try "Jump to Definition" or "Jump to References" within a .py file or between .py files, it works fine.

But I try the same features in a notebook (.ipynb), it only works within the same notebook. That means:

• I cannot jump to definition/references if I defined a function etc. in another notebook, even though Shift + Tab shows the definition, signature etc.

• I cannot jump to definition/references if the definition is in a .py file, even though Shift + Tab shows the definition, signature etc.
  "No jump targets found" message pops up.

Which language server are you using?

Does it also happen if you were to use python-lsp-sever instead?

So sorry for the late response due to my workload. I had finally time to try your suggestion. But yes, I see the same issue with python-lsp-server.
