Support for Remote in IW window

Issue Type: Bug

i have a .py file i run in an interactive window with cells first i start a jupyter server in a WSL, then connect to it when i try to run any cell, i get the error “Invalid response: 501 Not Implemented”

the server is started in the exact same working directory as the visual studio workspace

this doesnt always happen, i have a second jupyter server running in a different directory serving a different workspace and i can run interactive files no problem. Both use the same WSL and interpreter within it

I can replicate this issue. Here’s what i’m doing:

• Spinning up Jupyter and copy the URL
• Setup that URL & open interactive window, and i get 501 error
• Exact same process in VS Code 1.59 with webview interactive works Hence marking this as a regression.

On Linux, downgrading from the most recent version (v2021.8.1236758218, released 16 days ago) to the previous version (v2021.8.1195043623, released 29 days ago) fixed the issue for me. Given when this issue was created, I think it’s clear that the problem starting happening with the most recent release.
