title: Polymer 1.0 - How to bind html value
body: <p>I have a list of items in which each item has a .content html value as following. </p>
  
  <pre><code>  &lt;template is="dom-repeat" items="{{entries}}"&gt;
      &lt;li&gt;&lt;p class="paper-font-body2"&gt;{{item.title}}&lt;/p&gt;
        &lt;div&gt;{{item.content}}&lt;/div&gt;&lt;/li&gt;
    &lt;/template&gt;
  </code></pre>
  
  <p>content field is somewhat like this </p>
  
  <pre><code>  Hello &lt;strong&gt;Polymer&lt;/strong&gt;
  </code></pre>
  
  <p>It shows in browser as plain text. How do I show it as safe html?</p>
  
  <p>EDIT: this issue is <a href="https://github.com/Polymer/TemplateBinding/issues/57" rel="noreferrer">raised</a>, but it doesn't help me.  </p>
