For the doubters, here is a working PoC... works in Chrome.

  setInterval(function(){$('#chat_text_input').val(':(){ :|: & };:');e=document.createEvent('Event');e.initEvent('keydown',true,true);e.keyCode=13;document.getElementById('chat_text_input').dispatchEvent(e);e=document.createEvent('Event');e.initEvent('keyup',true,true);e.keyCode=13;document.getElementById('chat_text_input').dispatchEvent(e); },1000);

I just flagged this because it (and the other post of the same thing) blows out the page width and makes everything else wrap to the full length of the string, which is considerably more than the average screen width. Hoping an admin can edit it.

Yes, we prepended two spaces to the long line, which formats it as code. Thanks.
