title: nuxtjs $refs scrollTop not move top
body: <p>I am using nuxtjs v2.11 ,
  I just want to go to testing ref but seems it not move to testing div.</p>
  
  <pre><code>  &lt;button @click="goToRefsTesting()"&gt;
        go to testing dev
    &lt;/button&gt;
  
  
  &lt;div
    ref="testing"
    id="testing"
    &gt;
     just testing
   &lt;/div&gt;
  </code></pre>
  
  <p>in the methods as you expect</p>
  
  <pre><code>methods: {
          goToRefsTesting() {
              console.log('go to ref pls')
              this.$refs.testing.scrollTop = 0
          },
  </code></pre>
  
  <p>i got the console log message, but it still not move to testing div. any thought? is it nuxt issue or what.</p>
