title: VS Code's flake8's ignore arguments don't work on format on save?
body: <p>Here is my settings.json:</p>
  <pre class="lang-json prettyprint-override"><code>{
      &quot;python.pythonPath&quot;: &quot;/home/zhaodachuan/anaconda3/envs/ranking_engine/bin/python&quot;,
      &quot;python.autoComplete.extraPaths&quot;: [
          &quot;/mnt/c/Users/hnjyz/OneDrive/jupyter_lab/code/ranking_engine&quot;,
      ],
      &quot;python.linting.pylintEnabled&quot;: false,
      &quot;python.linting.enabled&quot;: true,
      &quot;python.linting.flake8Enabled&quot;: true,
      &quot;python.linting.flake8Args&quot;: [
          &quot;--max-line-length=120&quot;,
          &quot;--ignore=E402,F401&quot;,
      ],
  }
  </code></pre>
  <p>But the <code>flake8</code> <code>--ignore</code> doesn't work when I turn on the <code>format on save</code> in VS Code.</p>
  <p>What should I do?</p>
