Re: [csswg-drafts] [css-ui] Unprefix 'appearance' and/or make the spec web-compatible

If you suggest that `appearance` should be available in author sheets, then it seems likely to me that some authors will start using the "internal" `appearance` values and then we'd have an even bigger mess to sort out eventually...

Fwiw, Gecko can make individual property values available in the UA-sheet only. For example `-moz-menulist-button`, which we set in the UA-sheet on the `<select>` disclosure button, is an invalid value in an author sheet and simply doesn't parse there.  I think this is the mechanism we'll use to deprecate `-webkit-appearance` values that we need internally but aren't needed for web-compat.

Would it be possible for other UAs to parse a different set of values for UA/author sheets?
