Test Case + Fix

Setting input.value on an &lt;input&gt; field does not reliably redraw if it has placeholder text when that &lt;input&gt; has been generated programatically. This leads to situations where the input.value is displayed *on top of* the placeholder text.

Steps to reproduce:

1) Generate a new &lt;input&gt; via javascript
2) Assign this &lt;input&gt; a placeholder attribute
3) Append &lt;input&gt; to the document.body
4) Set the value of the &lt;input&gt; (w/timeout as this won't happen immediately)
5) Notice that the input.value is displayed on top of the placeholder

The workaround is to toggle input.readOnly on/off again while setting input.value (see attached).</pre>
