Id attribute get lost

[Flavien CROCHARD]

Paste this code in source mode (config.enterMode is set to CKEDITOR.ENTER_BR):

<div id="body">
  foo
</div>

In wysiwyg mode, push enter after foo and click on one of the bullet buttons. Back to source mode, the ul tag is outside the div element.

Expected result :

<div id="body">
  foo
  <ul>
    <li>
      &nbsp;
    </li>
  </ul>
</div>

Actual result :

<div id="body">
  foo
</div>
<ul>
  <li>
    &nbsp;
  </li>
</ul>

I have been able to reproduce it in all browser in all enter modes (not only CKEDITOR.ENTER_BR) from CKEditor 3.0
