I’m seeking WebKit’s position on the following features in css-pseudo and css-text-decor: • ::spelling-error highlight pseudo-element [0] • ::grammar-error highlight pseudo-element [1] • text-decoration-line: spelling-error [2] • text-decoration-line: grammar-error [3] While these features span two specs, they might be worth considering together, because the new pseudo-elements depend on the new text- decoration-line values for UA stylesheet support (and to be most useful to authors). Note that there’s a bug with a WIP patch for the pseudo-elements [4].
