title: Expand Transition is not smooth
body: <p>I have a problem with strange behavior for expand transition. Transition is not smooth for some reason. It stops for a moment before disappearing - just like:</p>
  
  <p><a href="https://i.stack.imgur.com/UTi5T.gif" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/UTi5T.gif" alt="Not smooth transition"></a></p>
  
  <p>Template is as simple as</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;template&gt;
    &lt;v-expand-transition&gt;
      &lt;v-alert
        v-if="visible"
        prominent
        type="error"&gt;
        &lt;v-row align="center"&gt;
          &lt;v-col class="grow"&gt;
            {{message}}
          &lt;/v-col&gt;
          &lt;v-col class="shrink"&gt;
            &lt;v-btn @click="invoke"&gt;{{button}}&lt;/v-btn&gt;
          &lt;/v-col&gt;
        &lt;/v-row&gt;
      &lt;/v-alert&gt;
    &lt;/v-expand-transition&gt;
  &lt;/template&gt;
  </code></pre>
  
  <p>How to fix it? 
  I'm on latest stable chrome for windows (83.0.4103.61 x64)</p>
