title: Vue.js data-bind style backgroundImage not working
body: <p>I'm trying to bind the src of an image in an element, but it doesn't seem to work. I'm getting an "Invalid expression. Generated function body:  { backgroundImage:{ url(image) }".</p>
  
  <p>The <a href="http://vuejs.org/guide/class-and-style.html#Object_Syntax-1" rel="noreferrer">documentation</a> says to use either 'Kebab-case' or 'camel-case'.</p>
  
  <pre><code>&lt;div class="circular" v-bind:style="{ backgroundImage: { url(image) }"&gt;&lt;/div&gt;
  </code></pre>
