sourceURL containing space does not work

[sapphi-red]

Describe the bug When // #sourceURL= has an URL containing space, the transformed file is shown instead of the original file.

To Reproduce Steps to reproduce the behavior:

1. Clone https://github.com/ondrejrohon/sveltekit-debug-vscode in a path containing a whitespace (e.g. C:\Users\green\foo bar\sveltekit-debug-vscode)
2. Click this button
3. Open http://localhost:5173
4. See the transformed file (IIFE named anonymous) is shown instead of the original file (ESM exporting load function).

Log File vscode-debugadapter-e6485847.json.gz

VS Code Version: 1.93.1

Additional context It did not work even if I escaped the space with %20.

Original issue: https://github.com/vitejs/vite/issues/17977, https://github.com/sveltejs/kit/issues/12625

The string you put in there is not a valid URL. File URLs should generally begin with file:///. Encoding it as a URL properly will allow for escaping of spaces.

This is not a behavior controlled by the debugger, source URL parsing happens in V8/Chrome and in your case it's not parsing correctly:
