Bug or Feature? - Round Two

Round Two - Safari changes your styles did you know?

Other rounds: [One|Two|Three|Four|Five]

We're back again with another round of "Bug or Feature?" (see round one) highlighting a particular behavior in one or more browsers, that, well, could be a Bug, or it could be a Feature... we'll open up the comments for your vote and opinion.

Alright, what's todays "Bug or Feature"?

Synopsis:
In Safari, usability of textarea elements has been greatly improved by allowing the user to decide how wide and how tall it should be, by making a grippy that the user can drag to stretch. Its a great feature, that many other browsers are looking into (Ask ASA, it's on his top 10 for Mozilla Firefox).

What is interesting, is that as a developer, if you ask for the .innerHTML of an element that wraps a textarea in JavaScript, it will report back exactly what you supplied... *except* if the user changed the dimensions of the textarea, the style attribute is now filled with margins, paddings, width and height values that you didn't specify.

If I have the following HTML, I would expect it to return the same content:

Example HTML snippet:

<div>
<textarea name="a_textarea" cols="40" rows="4">
  Hello World
</textarea>
</div>

Expected [div].innerHTML returned:

<textarea name="a_textarea" cols="40" rows="4">
  Hello World
</textarea>

Question:

If the user stretches the textarea in Safari (or later in other browsers), and you asked for the .innerHTML and got something different than the HTML fragment above...

Try it yourself.
