[["-webkit-mask-box-image-slice", "0 fill"],
 ["stroke-color", "rgba(0, 0, 0, 0)"]].forEach(([property, initial]) => {  
  ["", "initial", "inherit"].forEach((value) => {
    test(() => {
      const el = document.createElement("span");
      document.body.appendChild(el);
      el.style[property] = value;
      const cs = window.getComputedStyle(el);
      assert_equals(cs[property], initial);
    }, property + ": " + value);
  });
});

shows this is actually just the initial keyword generally?

Neither property has any defined value in html.css, so I don't know why there's any difference here.

Note that mask-border-slice, which per Compat -webkit-mask-box-image-slice is an alias of, should per spec have an initial value of 0 (as it gets with the initial keyword!) rather than the current "0 fill".
