Description

Editing an image in a Text Editor module pops a malformed layout

Steps to reproduce

Drag in a Text Editor module, then click Add Media to insert an image. Before inserting this image, try to edit it, and you will see an interface like this: http://i63.tinypic.com/29uwww1.png

After inserting, if you try to edit this image, you will see an interface like this: http://i63.tinypic.com/123bg2g.png (for this one, not sure if it also has any CSS issues or it's by design)
