Hidden fields wrapped around with div in form helper

[eluser]steelaz[/eluser]
Is there a good reason why form helper wraps hidden fields with div (inline "display:none")?

I almost certain it doesnt.

Code

Code:

<p>
&lt;?=form_hidden('user_id', set_value('user_id', '9' ));?&gt;
&lt;?=form_submit('mysubmit', 'Update User!');?&gt;
</p>

Generated

Code:

<p>
&lt;input type="hidden" name="user_id" value="9" /&gt;
&lt;input type="submit" name="mysubmit" value="Update User!"  /&gt;&lt;/p>
