They do, at least obliquely. In summary: the issue is that if everything else about Newton’s model was right except that gravity was delayed, orbits would be wrong. But, actually, it turns out, as Einstein theorized and later evidence supported, everything (well, enough) else about Newton's model turns out to be wrong, too.
