Clicking a CSS path from inspector fails with remote environment

If you open a repo using a VS Code remote environment (issue has been tested on WSL + Containers, assuming it’s the same in SSH) and try to click on a link to a CSS file in the inspector (source map generated or otherwise) the file fails to load.

After some debugging I found that the following error was being generated:

rejected promise not handled within 1 second: Error: cannot open file:///vscode-remote%3A/wsl%252Bubuntu/home/aaron/code/github/supercharging-web-dev-toolbox/src/pages/CreateGame.module.css.

My debugging shows that the line that the error comes from is https://github.com/microsoft/vscode-edge-devtools/blob/main/src/devtoolsPanel.ts#L309

I’ll use comments to detail my findings around a possible fix

Thanks for bringing awareness to this bug, probably fell through the cracks. Adding @codepo8 and @hkal to raise visibility.

This has unfortunately gotten stale. Let me ping @vidorteg again to put this back on his radar. It’d be good to track this regression and work on a fix.
