title: Android webview fullscreen on videos not working
body: <p>In my webview videos aren't able to be displayed in fullscreen. The chrome console shows the following error when I press the fullscreen button on e.g an youtube video.</p>
  <pre><code>Uncaught (in promise) TypeError: fullscreen error
  </code></pre>

  <p>System</p>
  <pre><code>Android 10
  Chrome version: 83.0.4103.106
  </code></pre>
  <p>App configuration</p>
  <pre><code>compileSdkVersion 28
  defaultConfig {
      minSdkVersion 22
      targetSdkVersion 28
  }
  
  webviewSettings.setJavaScriptEnabled(true);
  webviewSettings.setDomStorageEnabled(true);
  webviewSettings.setSupportMultipleWindows(false);
  webviewSettings.setJavaScriptCanOpenWindowsAutomatically(false);
  </code></pre>
  <p>The error is related to this bug <a href="https://bugs.chromium.org/p/chromium/issues/detail?id=945287" rel="nofollow noreferrer">Bug 945287</a> however it should be fixed in my version. Are there any other settings required to display embedded videos in fullscreen in a webview?</p>
