"Run Cell" won't work with cell under list item using a letter

I'm using using quarto with the vscode extension. When I have a python cell as part of a sub-list item and I run the cell, it attempts to run the whole cell along with the fenced code delimiter . Here is an example:

---
title: "Code Cell In Sublist"
format: typst
---

Here is a list with some code cells

1.  This is item 1. 

    a.  this is item 1.a

        ```{python}  
        # Run Cell doesn't work since ```{python} is sent
        print("Hello from item 1.a")
        ```

2.  This is item 2. 

    ```{python}
    # Run Cell works. ```{python} is not included
    print("hello from item 2")
    ```

quarto version: 1.4.550
quarto extension 1.111.0
jupyter extension 2024.2.0
windows 10

Note that this document renders perfectly with item 1a indented more than the code in item 2. It's just that the interactive portion isn't working.

Reproduce the issue in the VS Code extension using the supplied Quarto document, focusing on the Run Cell action for a Python cell nested under a lettered list item. No source file or test is named; trace the Run Cell entry point and compare it with the working numbered-list case. Done means the nested cell sends only its Python body, without the fenced-code delimiter, while the existing case continues to work.
