Similar to #11053, the css-ui-4 has a redundant group around the
outlineproperty value. It is currently specified as[ <'outline-width'> || <'outline-style'> || <'outline-color'> ], but I think it could be better expressed without the[], as<'outline-width'> || <'outline-style'> || <'outline-color'>instead.I'd like to point out that
carethas similar shape, and is expressed as<'caret-color'> || <'caret-animation'> || <'caret-shape'>. So I think both should be have a consistent syntax.
