title: Uib-tooltip with html unsafe
body: <p>I have a problem with my tooltip.
  I have something like this</p>
  
  <pre><code>&lt;span uib-tooltip="{{displayName()}}"&gt;&lt;/span&gt;
  </code></pre>
  
  <p>and in js file</p>
  
  <pre><code>function displayName() {
  return '&lt;div&gt;' + 
       name +
      'div' +
      '&lt;b&gt;something&lt;/b&gt;'
  }
  </code></pre>
  
  <p>So I have escape characters and I don't know how to deal with it. Obviously, I would like to display in my tooltip properly code, without
      "div" etc. </p>
  
  <p>How can I deal with it? I know that earlier we can use tooltip-html-unsafe, but it's deprecated now. </p>
