Perspective widget does not load in VS Code

[s1lvester]

Edited by Don, as the widget does not load in regular desktop (not just SSH or the like).

## Environment data - VS Code version: 1.87.2 - Jupyter Extension version: v2024.2.0 - Python Extension version: v2024.2.1 - OS (Windows | Mac | Linux distro) and version: NT x64 10.0.19045 on Client, Ubuntu 20.04 on remote. - Python and/or Anaconda version: 3.9.18 - Type of virtual environment used: N/A - Jupyter server running: Remote-SSH ## Expected behaviour Widget-Download from `"jupyter.widgetScriptSources": ["jsdelivr.com", "unpkg.com"]`, should be downloaded locally, when "Download Extensions Locally" is configured in Remote-SSH. Alternatively vscode-jupyter should use the extension.js from the remote-host from `~/.local/share/jupyter/nbextensions/` or `~/.local/share/jupyter/labextensions/` ## Actual behaviour vscode-jupyter tries and fails to download ScriptSources from "jsdelivr.com", "unpkg.com" - which leads to a timeout, since the remote is "airgapped" In this concrete case the Widget-files in - `~/.local/share/jupyter/nbextensions/@finos/perspective-jupyterlab` - `~/.local/share/jupyter/labextensions/@finos/perspective-jupyterlab` are ignored even though there seems to be logic implemented to search for these as documented here: https://github.com/microsoft/vscode-jupyter/wiki/Component:-IPyWidgets#loading-3rd-party-source ## Steps to reproduce: 1. Install vscode remote-ssh with python and vscode-jupyter. 2. Configure remote-ssh to download all extensions locally (`"remote.downloadExtensionsLocally": true,`)  3. Install and run a python package that uses a Widget - in this case "perspecitve":(https://perspective.finos.org/docs/python/#perspectivewidget) 4. vscode-jupyter is unable to download from jsdeliver.com and unpkg.com, since the remote has not internet, which leads to a timeout.  ## Validation Widget works fine I when I start a Jupyterlab Server on the Remote Host and Access it via https in a Webbrowser:  ## Logs

## By the way I still think this is somewhat related to https://github.com/microsoft/vscode-jupyter/issues/14762 because vscode-jupyter could just reference the widget files from the remote-host?

Please could you enable logging as follows:

• Open settings & go into Jupyter->Logging
• Change the value to verbose
• Reload VS Code,
• Attempt to repro the issue & then copy the output from the Jupyter output panel.

I'm interested in the python env used to run the cells. And some entries like getDataDirsImpl in the logs. Feel free to obfuccate paths (e.g. removing user names, we already do that). However I'd appreciate it if you can leave most of the logs intact, that.s

OK here's the dump.
