On Redactor's website, they provide a demo with an image that you can click on and drag around the editor to relocate it among the text.

Trying this same functionality in the rich text editor in the Craft control panel doesn't work though. I even copied the demo HTML from Redactor's website and pasted it into Craft, without any luck.

Has anybody been able to get this working or have any idea why this functionality would be missing in Craft?
