title: Keep material design lite tooltip visible after hover
body: <p>Is it possible to keep a material design lite tooltip open after hovering over it? So for example a user can click on a link in it.</p>
  
  <pre><code>&lt;div id="myTooltip" class="icon material-icons"&gt;info&lt;/div&gt;
  &lt;div class="mdl-tooltip mdl-tooltip--large" for="myTooltip"&gt;
    &lt;a href="#"&gt;Here&lt;/a&gt; is the further information.
  &lt;/div&gt;
  </code></pre>
