title: textarea focus event takes place so many times unwantedly in Chrome
body: <p>Pretty simple JS:</p>
  
  <pre><code>$(".input").focus(function(){
  
      alert("input clicked");
  
  });
  </code></pre>
  
  <p>HTML:</p>
  
  <pre><code>&lt;textarea class="input"  style="height:20px" cols="60"&gt;&lt;/textarea&gt;
  </code></pre>
  
  <p>In Chrome so many alerts are received but in FF, all is ok.</p>
  
  <p>If I use 'click', instead of 'focus', then in Chrome, focusing the textarea very gently launches no alert box but it does get focused. I tested the focusing with some default text getting changed (not mentioned in the code).</p>
  
  <p>I want to make a status update box just like Facebook. When the user focuses the textarea, it will expand horizontally with new content.</p>
  
  <p>What is the way that Chrome and all other browsers will behave in the same way (producing the alert only once)?</p>
