title: Electron frame: false not working
body: <p>for some reason in my electron app, whenever I set <code>frame: false</code> in <code>BrowserWindow</code> options, the frame still persists in windows 10 (build 1709), and does not disable. Here is my <code>BrowserWindow</code>:</p>
  
  <pre><code>const win = new BrowserWindow({
      webPreferences: {
          width: 1440,
          height: 960,
          frame: false,
          titleBarStyle: 'hidden',
          nodeIntegrationInWorker: true,
          nodeIntegration: false
          // devTools: false
      }
  });
  </code></pre>
  
  <p>I've tried removing everything except <code>frame: false</code> even, to no avail. My friend also claims his window frame is also not being removed on his Mac as well. I'm currently using electron version 1.8.2.</p>
