5666	CKeditor 3.2.1 : the attribute class is inserted by CKeditor	Alex Medina		"CKeditor 3.2.1 : the attribute class is inserted by CKeditor

Tested on FireFox
- Empty the CKeditor textarea content
- click on Source button
- Paste the following html source 
<p class=""pa1"">
	this is a paragraph with class defined</p>
- click on Source button again
- enter one or two paragraphs such as (without the quotes)
""this is a new paragraph""
""this other line should does not have a class attribute defined""
* Note how the newly added paragraphs have the same class name as the first paragraph.

Please test other attributes as well.
I don't think CKeditor should reuse the last tag's attributes. If so, please cofirm that this is how CKeditor works."	Bug	closed	Normal		General	3.2.1	invalid
