I didn't see the following argument mentioned yet. (Sorry if somebody did and I missed it.) The size of a shadow is unpredictable when the shadow is blurry. We don't define the precise algorithm for the blur, but I imagine the intensity of the shadow diminishes with something approximating a Gaussian curve. At some point, the shadow intensity will be less than can be expressed within the color depth of the screen, but where that point is is not easily known. The page author certainly can't predict it.
