Doesn't give any indication of differing HREF attributes on an A tag

Just like the title. We have a change review page for a CMS system. 
Users were changing the href of A tags, and it didn't make any ins/del tags around those in any way to indicate it. 

So wound up having to HtmlEncode the CMS HTML and then diff on that vs. the current version (also HtmlEncoded) instead of on the actual HTML.
