title: Aria-label is not working in Chrome and Firefox with NVDA
body: <p>I have a simple textbox:</p>
  
  <pre><code>&lt;input type="text" aria-label="First Name" title="First Name" /&gt;
  </code></pre>
  
  <p>I am showing the tooltip <code>First Name</code> on hover of textbox.</p>
  
  <p>I used the <code>aria-label</code> as well as <code>aria-labelledby</code> but neither are working with Chrome or Firefox.</p>
  
  <p>It's working on selection of the textbox, but not working on mouse hover.</p>
  
  <p>But it's working fine with IE on mouse hover as well as on textbox select.</p>
  
  <p>I am using the screen reader NVDA.</p>
