SyntaxError: invalid syntax

[willfliaw]

Describe the bug
When using VSCodium to write Jupyter notebooks, entering the line %matplotlib inline causes a red squiggly line to appear under %, indicating a SyntaxError: invalid syntax. This is incorrect behavior since %matplotlib inline is a valid IPython magic command for Jupyter notebooks.

Please confirm that this problem is VSCodium-specific

• This bug doesn't happen if I use Microsoft's Visual Studio Code. It only happens in VSCodium.

Please confirm that the issue/resolution isn't already documented

• I checked the Docs page and the Troubleshooting page, and my issue is not mentioned there.

To Reproduce
Steps to reproduce the behavior:

1. Open VSCodium.
2. Install the Jupyter extension.
3. Create a new Jupyter notebook file (.ipynb).
4. Add the following line to a cell: %matplotlib inline.
5. Notice the red squiggly line under % and the associated SyntaxError: invalid syntax.

Expected behavior
VSCodium should recognize %matplotlib inline as a valid IPython magic command when editing Jupyter notebooks and should not flag it as a syntax error.
