OS/Web Information

• Web Browser:
  chrome firefox
• Local OS:
  ubuntu20.04
• Remote OS:
• Remote Architecture:
• code-server --version:
  4.95.1 4.95.3 latest

Steps to Reproduce

1. Use the official image: linuxserver/code-server:latest.
2. After running the container, install the latest version of Jupyter (2024.11) in the opened VSCode.
3. Install Anaconda through the terminal in VSCode.
4. Create a Jupyter notebook.
5. Clicking "+cell" in the interface shows no response, but the cell is actually added.

Expected

.ipynp file contents can be displayed, and "+code" button effective.

Actual

The actual situation is: whether I create a new notebook or import an existing .ipynb file with content, nothing is visible in the file content interface. However, it can run successfully. Additionally, after clicking "+code" and running it, the output shows a change in the line number, indicating that it works, but the content does not display. It still appears blank.

@benz0li That works for me! Thanks a lot.
