title: line break inside a list item generates space between the lines
body: <p>I want to break line <code>&lt;br/&gt;</code> inside a <code>&lt;li&gt;</code> 
  Like:</p>
  
  <ul>
  <li><em>First line<br>
  second line</em></li>
  <li><em>Second li</em></li>
  <li><em>third li</em></li>
  </ul>
  
  <p>but when doing so (both labels)- I get a space between them.
  margin and padding is 0 but still I get it..
  any idea how to get rid of it?
  Thanks!</p>
