It doesn't work to remove for custom Ui Widget.

Hi Everyone! I have customized ArrayFieldTemplate as UiSchema.

`const newUiSchema = {
      parents: {
        items: {
          'content': {
            'students': {
              'items': {
                'content': {
                  "ui:widget": props => {
                    return (
                      <StudentComponent value={imageFileProps.value} onChange={props.onChange} />
                    )
                  }
                }
              }
            }
          }
        }
      }
    };`

It's array json schema. If I am going to remove StudentComponent then the last StudentComponent is removed.

when call of onDropIndexClick, it doesn't work correctly.
