Sourcemaps broken in VSCode

[Beretta1979]

OS: Ubuntu 20.04
This occurs in Meteor 2.3.4, in Meteor 2.2.1 everything was working fine

The sourcemaps are not working anymore, the breakpoints are not getting hit.
The issue is introduced by this PR: #11013. If the changes of this PR are reverted everything is working fine.

This is my launch.json file:

{
  "configurations": 
  [ 
    {
      "name": "Launch Meteor server",
      "request": "launch",
      "type": "node",
      "restart": true,
      "port": 9229,
      "cwd": "${workspaceFolder}/projects/test",
      "runtimeExecutable": "npm",
      "runtimeArgs": ["run", "start:debug"],
      "outputCapture": "std",
      "console": "integratedTerminal",
			"sourceMapPathOverrides": {
                          "meteor://💻app/*": "${workspaceFolder}/projects/test/*",
			},
    }
  ]
}

I think that in tools/isobuild/bundler.js, process.env.ROOT_URL should never be added for base64 encoded source mapping URLs
