title: Ngx-Spinner is not working in feature module
body: <p><code>Ngx-Spinner</code> it is working fine when i call it in inside the main module i.e. <code>app-module</code>. </p>
  
  <p>I am using <code>line spinner</code> on complete page so i define it inside the <code>app-component.html</code></p>
