I have noticed that this class controls more views to the right of the URL in
location bar. Those views should also have a ripple. I have added the changes
here to have them working at the same time but I will see if some refactoring of
commonality is possible. Interestingly this class is already being the
WidgetObserver, have I seen this earlier it would have been easier with the
rest.

                                 public views::WidgetObserver {
  public:
   // ContentSettingImageView takes ownership of its |image_model|.
   ContentSettingImageView(ContentSettingImageModel* image_model,

                           const gfx::FontList& font_list,
                           SkColor parent_background_color);
