title: Windows Phone: Missing blur event in IE or Edge when back button pressed
body: <p>The following scenarios are relevant to Windows Phone devices (IE or Edge).</p>
  
  <p><strong>Scenario 1:</strong></p>
  
  <p>If an input element has the focus and the soft keyboard is up, pressing the hardware back key blurs the focused element and pops down the keyboard as it should. However, there is no corresponding blur event fired.</p>
  
  <p><strong>Scenario 2:</strong></p>
  
  <p>If an input element has the focus and the soft keyboard is up, tapping outside the input element blurs the focused element, pops down the keyboard and fires a blur event.</p>
  
  <p><strong>Question:</strong></p>
  
  <p>Is there a way to make the blur event fire when the hardware back key is pressed and an input element has the focus?</p>
  
  <p><strong>HTML to reproduce the issue:</strong></p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
      &lt;head&gt;
          &lt;meta name="viewport" content="width=device-width, user-scalable=no" /&gt;
          &lt;title&gt;Blur Test&lt;/title&gt;
      &lt;/head&gt;
      &lt;body&gt;
          &lt;p&gt;Blur Test&lt;/p&gt;
          &lt;input type="text" onblur="alert('onblur');"&gt;
      &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>Using addEventListener produces the same result.</p>
