14850	eventProcessors for radio and checkbox UI element definitions overwritten	AlexW		"https://github.com/ckeditor/ckeditor-dev/blob/master/plugins/dialogui/plugin.js#L1217 https://github.com/ckeditor/ckeditor-dev/blob/master/plugins/dialogui/plugin.js#L1291

At those lines the ui element definition is extended to provide a new `onChange` function but this causes the default `onShow`, `onHide` and `onLoad` events to be lost.


{{{
  type: 'radio',
  items: [['One', 1], ['Two', 2], ['Three', 3]],
  'default': 1,
  onLoad: function() {
    //Never gets called.
  },
}}}

Should this be done in the same way as it is for button?
