What are the steps required to reproduce the bug?
1. Create or edit a node (I am using Basic Page type for this)
2. Insert an image using the CKEditor media widget. Select "center" as the alignment. The image appears centered in the Editor pane.
3. Preview the node - the image is now left aligned.
4. Save the node.
5. View the node. The image still appears as left aligned.
What behavior were you expecting?
* Expecting the the image will be centered when align = center is selected.
What happened instead?
* The image is left-aligned.
Additional info:
* Left and Right alignment options work. Only center does not.
