title: Semantic-UI: Add line break in tooltip
body: <p>I want to have line breaks in my tooltip:</p>
  
  <pre><code>&lt;span data:data-tooltip="line 1 ...\n 
                                line 2 ..."&gt;
  </code></pre>
  
  <p>I tried several proposals from here:
  <a href="https://stackoverflow.com/questions/3340802/add-line-break-within-tooltips">Add line break within tooltips</a></p>
  
  <p>Nothing did the trick. I use it without Javascript (v.2.2)</p>
