title: The element which has v-show="false" attribution in prerendered page flickerings when opening the page
body: <p>It only occurs when I use prerender-spa-plugin to prerender a page. It invokes an element(a modal) which has <code>v-show="false"</code> attribution as default. But this modal always flickering when open the page even <code>v-show</code> never been true.
  I already has <code>v-cloak</code> in this element.
  What's the correct way in Vue style to avoid flickering?</p>
