Comment (by talldanwp):

 Hey @afercia, It'd still be good to get an understanding of why this
 button element is attached to the body. I think there could be two fixes,
 first perhaps making it so that the media uploader doesn't attach elements
 to the body, making this behaviour better encapsulated. Second,
 potentially changing the way media is initialised in the editor to avoid
 multiple instances.
