Cannot run lines in multiple interactive windows at the same time

Environment data

• VS Code version: 1.63.2
• Jupyter Extension version: 2021.11.1001550889
• Python Extension version: 2021.12.1559732655
• OS and version: Windows 10 2004
• Python and/or Anaconda version: 3.9
• Type of virtual environment used: N/A
• Jupyter server running: Local

Expected behaviour

Run two time-consuming codes in multiple interactive windows simultaneously, like in the 2021.10 version Jupyter.

Actual behaviour

The first window successfully executes the code, while the second window does not execute until the first window finishes.

Steps to reproduce:

Open an interactive window, and use “Run Selection/Line in Interactive Window” to send the following code.

while True:
   pass

Open a second interactive window, and use “Run Selection/Line in Interactive Window” to send the same code to the second window. The second window cannot execute the code unless we turn off the first window.
