13783	Class not removed if format was changed	Andreas Gyr		"

== Steps to reproduce ==

1. Visit http://sdk.ckeditor.com/samples/format.html and scroll down to ""Custom Text Format Definition"" 
2. Inside the Editor inspect the code below the ""The Algorithm"" heading. It is an <pre> Element with class ""formattedCode""
3. Click on the Code and Switch Fomat from to normal
4. Inspect the Code again. The Element is now <p> but the class is still there
5. Click Sourcecode twice
6. Now the class is gone

== Expected result ==
The class should be removed if format was changed.

== Actual result ==
The class is still there.
