DOM Assistant fails to match :empty if a node contains an HTML comment

[GoogleCodeExporter]

DOMAssistant should doesn't match :empty if a node contains only HTML 
commments. Probably an IE only bug since comments are traversable through the 
DOM

http://www.w3.org/TR/css3-selectors/#empty-pseudo

6.6.5.12. :empty pseudo-class

The :empty pseudo-class represents an element that has no children at all. In 
terms of the document tree, only element nodes and content nodes (such as DOM 
[DOM-LEVEL-3-CORE] text nodes, CDATA nodes, and entity references) whose data 
has a non-zero length must be considered as affecting emptiness; comments, 
processing instructions, and other nodes must not affect whether an element is 
considered empty or not.

Hi Keith, can you provide a test case?

I've attached a test case. Open it in IE8 and inspect the red bars with IE's 
developer tools and you'll see one / two HTML comment nodes. These should be 
ignored when checking for empty. 

DOMAssistant checks for .firstChild and since a comment node is a valid node in 
IE the test passes even though no content exists.

Hope that helps

Keith
