The Style combo is not context sensitive on editor recreation

[Frederico Caldeira Knabben]

1. Open the Ajax sample.

2. Type some text.

3. Select some text and apply the "Big" style in one of the words. Note that the style combo will be context sensitive when moving in/out that word.

4. Remove the editor.

5. Recreate it.

6. Open the Style combo so it gets loaded.

7. Click in/out the previously styles word.

The style combo will not be context sensitive anymore. Even when applying other styles, it will still not detect the current selection style properly.

To note that the styles list still shows the active styles properly.

This is another symptom of the shared CKEDITOR.config handled in #5345
