Display oembed in 3.5 media browser detail view

Currently, in the 3.5 media browser when opening an oembed attachment the icon is displayed.

Below a crude fix.

Add to plugins_loaded() method

add_filter( 'wp_prepare_attachment_for_js', array( $this, 'wp_prepare_attachment_for_js' ), 10, 3);

New method

public function wp_prepare_attachment_for_js($response, $attachment, $meta) {
        if( 'oembed' == $response['type']) {
            $oembed = $this->__getpreview($response['url']);
            $response['compat']['item'] .= "<script type='text/javascript'>jQuery('.thumbnail-oembed').html('{$oembed}');</script>";
        }
        return $response;
    }
