Incorrect. CSS box-shadows will typically look a lot better than image
shadows if the user zooms or prints. Also, CSS box-shadows do not stop
events from reaching the elements underneath them, which is very useful when
they're translucent; you can't emulate that with border images. Adding a
shadow to a border image is a lot of extra work that you can avoid using
box-shadow. It will also make the image bigger and slower to load.

Having border-image disable box-shadow would add a strange wart to the
platform that would confuse authors and prevent useful applications of these
features. The only benefit would be better fallback when border images are
not loaded or in browsers that support box-shadow but not border-image; but
the former is extremely unusual in practice and the latter is not worth
worrying about. In either case, falling back to no shadow at all is just
fine.
