 When add_theme_support('post-thumbnails') is not implemented, some admin
 buttons have style issues (no border/bg) in IE9. Some i've noticed are:
 - Add Media above wysiywg
 - Insert buttons bottom right of Add Media modal (buttons are essentially
 invisible once a file has been selected since text is white/no bg)

 The same thing happens for custom post types that don't support
 'thumbnail'
