title: Referencing a child component inside v-dialog
body: <p>I have a problem to get the reference of a component inside the component <em>v-dialog</em> of vuetify.</p>
  
  <p>This code prints <em>undefined</em> in console instead of the object.</p>
  
  <pre><code>&lt;template&gt;
      &lt;v-dialog ref="mydialog"&gt;
          &lt;v-card ref="mycard"&gt;
          &lt;/v-card&gt;
      &lt;/v-dialog&gt;
  &lt;/template&gt;
  
  &lt;script&gt;
  export default {
    mounted() {
        console.log(this.$refs.mycard);
    }
  }
  &lt;/script&gt;
  </code></pre>
  
  <p>Is not possible to access a child component by reference inside a <em>v-dialog</em> ? </p>
