title: is Content Security Policy 'unsafe-inline' deprecated?
body: <p>I'm developing a Chrome Extension, I tried to add the  'unsafe-inline' CSP as per the <a href="https://developer.chrome.com/extensions/contentSecurityPolicy" rel="noreferrer">Google Docs</a> </p>
  
  <p>However after doing so and attempting to reload my extension at <code>chrome://extensions/</code> I'm getting: </p>
  
  <p><code>There were warnings when trying to install this extension:
  Ignored insecure CSP value "'unsafe-inline'" in directive 'script-src'.
  </code></p>
  
  <p>For ref the entire CSF as defined in <code>manifest.json</code>: </p>
  
  <p><code>"content_security_policy": "script-src 'self' 'unsafe-inline'  https://localhost:8000; object-src 'self'"</code></p>
  
  <p>So, why am I not able to set 'unsafe-inline'?</p>
