Dl aren't being formatted

[alfonsoml]

go to source mode and insert

<dl>
<dt>Ticket created </dt>
<dd >The Globalization support has been introduced into the CKEditor prototype  </dd>
</dd>
</dl>

Now switch twice and the source won't be properly aligned.

For reference, I just copied some text to test for #2407 (I copied from the timeline page that turns out to be a big <dl>) and when I tried to create a list I got an error:

contentBlock.parentNode is null
http://localhost/fckdev/editor/_source/commandclasses/fcklistcommands.js
Line 322

But now it seems to work fine. Just in case anyone wants to try again.
