Would it be doable to parse them, but never match them? We do the same for the :-moz-placeholder pseudo-class for similar reasons... This would be slightly more tricky than just not parse them, at least until we get rid of them internally (if we do), but would allow pages using that kind of hacks to keep working. -- Emilio _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
