Interestingly some of the "failures" here seem to be caused by "uninitialized" fonts, meaning that now we trigger font loading by walking the glyphs and it has the side effect of making some of the tests fail. However those failures are actually progressions -and loading the same test in Safari shows the progressed variant (because we have the fonts initialized by some other means? -which we don't do when using wktr/drtr). Odd.
