 Certain attributes will override others. The image height attribute is
 overridden by the CSS style. So basically, if there was an image that was
 relying on the height attribute to set its height as something different
 than its actual size (e.g. the actual image file has a height of 100px,
 but the height attribute is 200px), then this CSS will override that.

 This is the reason why putting that CSS in will "fix" the image height
 attribute issue. It simply overrides the height attributes that have been
 applied with this update.
