title: Why blur and focus doesn't work on Safari?
body: <p>I have simple button like that:</p>
  
  <pre><code>&lt;button class="emoji-button-container" onblur="APP.hideEmojiContainer()" onclick="APP.toggleEmojiContainer()"&gt;
  </code></pre>
  
  <p>On Chrome both event works perfectly. </p>
  
  <p>On Safari onclick event works without any problem, but onblur event doesn't get triggered. Also element.blur() function doesn't trigger onblur event.
  I need it to work on Safari just like on Chrome, so what can I do? what's problem here?</p>
