Bug: Jupyter Notebook trim whitespaces not working in code cells

[hegerdes]

Does this issue occur when all extensions are disabled?: Yes
Note: All extensions disabled - except python and jupyter notebook

The function to trim whitespaces does not work in jupyter notebook code cells

• VS Code Version: 1.78.0 (252e546) - x64
• OS Version: Win 11 Pro

Steps to Reproduce:

1. Create a new Jupyter Notebook (.ipynb) file
2. Create a cell and put some code with tailing whitespaces and empty lines in it

Example:

It seems I can't reproduce in latest VS Code

@hegerdes can you please check if you can reproduce with all extensions disabled and also check if there is modified editor.trimAutoWhitespace setting in user setting or workspace.

@rebornix Thanks for your reply. I noticed that there was an update for VSCode formatting for notebooks, but it did not fix my issue. Thanks to your reply I also noticed that there are different trim settings: editor.trimAutoWhitespace and files.trimTrailingWhitespace. Both are set to true on my side. All extensions disabled.

What does not seem to work is the trimTrailingWhitespace part. Whitespaces on the end of the line and empty lines with whitespaces are not cleared. I created a short video for demonstration. See line 7,9 and 13.

I hope that helps differentiating the problem
