title: Pass in a slot with a reference value?
body: <p>In my component I have this scoped slot:</p>
  
  <pre><code>&lt;slot name="test"&gt;
      &lt;input ref="inputTest"&gt;
  &lt;/slot&gt;
  </code></pre>
  
  <p>In the parent I do this:</p>
  
  <pre><code>&lt;div slot="test"&gt;
      &lt;input ref="inputTest"&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>But when I tried to access the ref later in my component:</p>
  
  <pre><code>console.log(this.$refs.inputTest);
  </code></pre>
  
  <p>I get undefined.</p>
  
  <p>How can I pass in a slot that has a reference?</p>
