pkasting: Attached is a patch which fixes the issue. 
Patch ensures that any detach of the image element from the DOM also ensures
the image associated with the element (CachedResourceClient) is unregistered
with the CachedResource which was created while loading the image element. If
the CachedResource is not being referenced by any other client it is purged.
So, when the image element is reattached, it becomes new client which is
registered with the CachedResource and animation state is reset for it.
