What you're updating in your example script is the DOM value, not the HTML
attribute. I admit that this might be confusing at first sight, though what
you see is the expected behavior. See comment 13 of issue 4165
<https://code.google.com/p/fbug/issues/detail?id=4165#c13> for a more
detailed description why.
Btw. a similar thing happens for <textarea>. Compare the textContent
property with the value property.
