We can no longer use direction overrides to create the test vs reference renderings here, because of how harfbuzz now handles the numeral directionality internally. So it's difficult to come up with a testcase that verifies the exact rendering of the subtending mark + digit(s) combinations. What we can do, though, is verify that a single digit combines with the subtending mark without affecting its overall width; and that a double-digit number *does* increase the width. These two conditions are unlikely to both hold unless the rendering is behaving correctly. (FWIW, Chrome Canary passes these new test versions, as it also uses a recent harfbuzz; Safari currently fails, as Core Text doesn't support the subtending marks in the same way, if at all.)
