title: Empty heading warning on HTML5 validation
body: <p>I try to validate my HTML code and I have found this warning: Empty heading. <a href="http://validator.w3.org/check?uri=http://www.codetocode-developments.com/battle/&amp;charset=%28detect%20automatically%29&amp;doctype=Inline&amp;group=1&amp;user-agent=W3C_Validator/1.3%20http://validator.w3.org/services" rel="noreferrer">See here</a></p>
  
  <p>Obviously the heading is not empty. The content of the <code>&lt;h3&gt;&lt;/h3&gt;</code> is generated, in WordPress, by <code>the_title()</code> function. So, I don't understand why is this happen.. Somebody can explain me what is the problem? Thanks!</p>
