title: Can't set breakpoints on NPM Link'ed library
body: <p>I learn React JavaScript and now I have this problem<br />
  I Fork the <a href="https://github.com/iamhosseindhv/notistack" rel="noreferrer">notistack library</a> in GitHub then download my fork with Git Desktop so the project are on Windows 10 here  D:/git/notistack.</p>
  <p>After following <a href="https://docs.npmjs.com/cli/v7/commands/npm-link" rel="noreferrer">npm-link doc</a> it all work ok I can debug run the <a href="https://github.com/iamhosseindhv/notistack" rel="noreferrer">notistack library</a> typescript project in VScode.</p>
  <p>I &quot;npm link&quot; on my  <a href="https://github.com/iamhosseindhv/notistack" rel="noreferrer">notistack library</a> and &quot;npm link notistack&quot; in my ReactJs project all standard procedure and I can debug run the library ok.
  I make changes and rebuild <a href="https://github.com/iamhosseindhv/notistack" rel="noreferrer">notistack library</a> and I see it's working ok.</p>
  <p>But when I set up launch.json like this, with the <a href="https://code.visualstudio.com/docs/nodejs/nodejs-debugging#_common-questions" rel="noreferrer">runtimeArgs</a>, that suppose to enable debugging I can't make breakpoints work in the Library.</p>
  <pre><code>{
    &quot;version&quot;: &quot;0.2.0&quot;,
    &quot;configurations&quot;: [
        {
          &quot;name&quot;: &quot;Launch Edge&quot;,
            &quot;request&quot;: &quot;launch&quot;,
            &quot;type&quot;: &quot;pwa-msedge&quot;,
            &quot;url&quot;: &quot;https://localhost:6545&quot;,
            &quot;webRoot&quot;: &quot;${workspaceFolder}&quot;,
            &quot;runtimeArgs&quot;: [
              &quot;--preserve-symlinks&quot;
          ],
        }
    ]
  }
  </code></pre>
  <p>I set breakpoints in the ReactJs project node_module/notistack library but VSCode is setting them as unbound breakpoints.</p>

  <p>I suspekt it has something to do with that that notistack library is a Typescript project maybe and I link to a ReactJs project. any idea?
  Please advice what I need to check and do?</p>
