title: Vuejs component is not loaded by using webpack
body: <pre><code>import Vue from 'vue'
  import ProductEdit from './ProductEdit.vue'
  import App from 'components/App.vue'
  
  new Vue({
    el: '#page',
    components: {
      'app': App
    },
    render: h =&gt; h(ProductEdit)
  })
  </code></pre>
  
  <p>Why is <code>ProductEdit</code> rendered, but <code>App</code> is not?
  Here's my html file:</p>
  
  <pre><code>{% load render_bundle from webpack_loader %}
  
  &lt;div id="page"&gt;
      &lt;h1&gt;TEST&lt;/h1&gt;
      &lt;app&gt;
  
      &lt;/app&gt;
  &lt;/div&gt;
  
  {% render_bundle page %}
  </code></pre>
  
  <p>Moreover, the "TEST" header is also not rendered. How can I debug this? The console doesn't show any errors.</p>
  
  <p>EDIT:
  I also tried without render function and it didn't help.</p>
