Steps to reproduce the issue:

1. Create a new .qmd file
2. Create a new Python cell

import pandas as pd
import numpy as np

a = 1
b = 2

3. Place the cursor in the first line and press Ctrl + Enter

What did you expect to happen?

The code run only the first line

Were there any error messages in the output or Developer Tools console?

There was no error but the it run the whole code cell, not line by line
