Autocomplete stops working with multiple tabs

Discussion

Over the past weeks I have a very frustrating issue: autocomplete stops working when I use multiple tabs. I have this issue both with a private pro (trial) account and pro business account.

I can reproduce the problem like this:

  1. Start Cursor.
  2. Start coding in a notebook (autocomplete works as it should).
  3. Open/go to another notebook in a new tab.

Autocomplete now stops working. It does not work in any notebook opened.

The chat and Command-k still works. Only autocomplete is not working.

The only way to get autocomplete to work again is by restarting Cursor.

I have done a complete reinstall of Cursor. Does not help. I have only standard Python and Jupyter extensions installed. I have tried with different Cursor accounts, including a business account.
Version: 0.48.7 (Universal)
VSCode Version: 1.96.2
Using MacOS 15.4.

Any ideas?

This is follow-up details to my posted question. I have noticed the following phenomenon:
When autocompletion stops working in a notebook tab, switch to an open tab with a standard python file (that is, not a notebook). Autocomplete will suddenly be triggered! I can now go back to the notebook tab and autocompletion works again.

Although this seems to do the trick, the question remains: why does autocompletion stop working in notebooks?
