Cell numbering is broken for notebook/lab 7 (Anaconda)

[dbpengra]

Description

After 3 fresh installs of Anaconda (2 on Windows 11, 1 on Rocky Linux 9), followed by conda update --all, Jupyter Notebook 7.2.1 or JupyterLab 4.2.3 shows incorrect cell numbering as the cells are executed. In the example shown, the numbers skip values:

This behavior is not seen when running JupyterLab from the server provided by University of Washington IT (where I work), nor on the Jupyter "Lite" version available at Jupyter.org:

If I install the nbclassic version of the notebook, the numbering problem does not appear. I have not tried to install the package outside of Anaconda, and it may be an Anaconda bug.

Context

• Operating System and version: Rocky Linux 9.4 or Windows 11, 23H2
• Browser and version: Firefox 115.12.0esr or Google Chrome 126.0.6478.127

• Jupyter Notebook version: Linux = 7.0.8, Windows = 7.2.1

A follow up: User krassowski on the Jupyter Community Forum suggested that an extension may be to blame for the bug. It appears he is correct. When I disabled the "Anaconda Assistant" extension which is associated with the green "magic sparkles" icon seen in the active cell, the cell numbering problem disappeared. To do this, I followed the instructions in the JupyterLab User Guide on Extensions, sepecifically Managing Extensions with jupyter labextension.

Thus, the following from the command line:

jupyter labextension disable @anaconda/assistant

did the trick. So, Anaconda people need to fix this, I think.

Thank you for opening this issue @dbpengra! I will go ahead and close this issue here since it is not an issue in the Notebook codebase. I will also report this and I'll post updates here on reporting issues in @anaconda/assistant!

Fix for this was applied in @anaconda/assistant v4.0.21!
