--- Comment #9 from Hyongyoub Kim <hyongyoub.kim at navercorp.com> ---
I know this issue has seen no action for 9 years. Here is a ping that this issue does matter in the real world. Many sites use this "load the same source twice + onload event" technique to load images asynchronously and then display them when they are already in the memory cache.

Looks like Chromium fixed this last year.

The second load event does not fire because the following check in ImageLoader.

http://trac.webkit.org/browser/trunk/Source/WebCore/loader/ImageLoader.cpp#L217

Tried simply pretending the images are always different. It seems to work okay, but not sure about any side effects this would have on CachedImage::didAddClient and CachedImage::didRemoveClient.
