title: Why VS Code contains emphasized items but no error?
body: <p>I'm writing a React project in VS code. I met this problem in VS code. In my project, this folder <strong>shows Contains emphasized items</strong> and I know it means there is an error in my files. But in the picture:</p>
  <p><img src="https://i.stack.imgur.com/7wfRW.png" alt="vs code project" />,</p>
  <p>I have checked all files but no error was found.  So this makes me feel confused.</p>
  <p>I have searched this problem on google and found a similar GitHub issue. <a href="https://github.com/Microsoft/vscode/issues/54960" rel="nofollow noreferrer">https://github.com/Microsoft/vscode/issues/54960</a></p>
