title: HTML5 Date Input 6 digit year
body: <p>I have a standard <code>&lt;input /&gt;</code> control on my form, decorated with <code>type="date"</code></p>
  
  <p>When rendered, it displays the correct watermark of <code>yyyy-mm-dd</code>, and you can <em>select</em> a date correctly.<br>
  However, when you try <em>type in</em> a value, the <strong>year</strong> extends to 6 digits, instead of four. I have added screenshots to help demonstrate the issue I'm having.</p>
  
  <p>Is anyone else getting this? I'm using Chrome ( Version 35.0.1916.153 m ) as my default browser.<br>
  I'd like a way to force a 4year input that doesn't involve extra JS.</p>
