My point is that such behavior would create differences in behavior 
depending on where the image is in the dom.

Once the page is loaded, one would expect all images to be available. 
Which would not be the case if images are not loaded, the one under 
canvas would have a different behavior.

I understand your point, loading stuff is not a free operation. I just 
think not doing it would make things even more complicated for content 
provider.
