 `WP_Widget_Media::get_instance_schema` has
 `"widget_{$this->id_base}_instance_schema"` filter.

 * `WP_Widget_Media_Image::get_instance_schema`
 * `WP_Widget_Media_Video::get_instance_schema`
 *  `WP_Widget_Media_Audio::get_instance_schema`

 are using array_marge. like this.

 {{{#!php
 $schema = array_merge(
                         parent::get_instance_schema(),
                         array(
                                 // setting for widgets.
                         )
                 );
 }}}

 So, Change by the filter, if same key exist, overwritten.
