title: uib-tooltip-html not working
body: <p>From version 0.14 of ui-bootstrap, it looks like uib-tooltip-html (previsously : tooltip-html-unsafe) does not work anymore... or not the way I used to have it work.</p>
  
  <p>Basicely, the 'tooltip' works when the 'tooltip-html' does not:</p>
  
  <pre><code>&lt;a href="#" uib-tooltip-html="UIB-TOOLTIP-HTML"&gt;UIB-TOOLTIP-HTML&lt;/a&gt;
  &lt;a href="#" tooltip-placement="right" uib-tooltip="UIB-TOOLTIP"&gt;UIB-TOOLTIP&lt;/a&gt;
  </code></pre>

  <p>And since ui-bootstrap doc lacks example regarding this directive, I cannot guess what I am doing wrong.</p>
  
  <p>Any idea?</p>
