This is another event upon which the task to determine an object's
respresentation must be queued:
* one of the element's ancestor object elements changes to or from
showing its fallback content
For example, on Acid2, the image for the eyes is nested below an object
that is designed to fail to load. This ensures the eyes will render as
the fallback of the failed parent object.
