title: Why is Chrome showing a "Please Fill Out this Field" tooltip on empty fields?
body: <p>I was contacted by my client saying that users complaint saying that some fields now show a tooltip with a message "Please Fill out This Field". I couldn't believe what I heard... but the client is right - using latest Chrome version some fields show a browser tooltip with this message even side by side with my validators!</p>
  
  <p>What's the problem? What am I missing?</p>
  
  <p>Thanks.</p>
  
  <p>EDIT:</p>
  
  <p>The HTML generated by my user control is as follows:</p>
  
  <pre><code>&lt;input name="tbMontante" type="text" maxlength="8" size="10" tbMontante" class="Montantetextfield" 
      FieldName="Montante" 
      Required="True" 
      AllowDecimalValues="True" 
  /&gt;
  </code></pre>
  
  <p>EDIT:</p>
  
  <p>My doctype is as follows:</p>
  
  <pre><code>&lt;!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"&gt;
  </code></pre>
  
  <p>Should my browser use HTML 5 to parse it?</p>
