title: Google Chrome --allow-running-insecure-content does not work
body: <p>The <strong>Google Chrome</strong> flag <code>--allow-running-insecure-content</code> does not work. I have confirmed that the executable is in fact running with this flag by seeing the command line args in the <code>chrome://version/</code> URL where it is clearly reflected.</p>
  
  <p>When I visit our internal <strong>Github</strong> enterprise instance, which is on <code>HTTPS</code> I cannot see our <strong>TeamCity</strong> build status icons as the URL is on <code>HTTP</code>. We have these icons in our <em>README.md</em> and I end up with these <code>(blocked:mixed-content)</code> errors in the <em>Dev Tools / Network</em> tab.</p>
