[css] Formatting removes useful space

[anthonyvdotbe]

Issue Type: Bug

When formatting the following CSS, the space between "(" and counter(foo) on the penultimate line is removed. This results in less readable code & an ugly asymmetry, since the space between counter(foo) and ")" isn't removed. Moreover, it currently triggers #147059

body {
    counter-reset: foo;
}

bar::before {
    counter-increment: foo;
    content: "(" counter(foo) ")";
}

We use beautifyjs as the underlying CSS formatter. Would you mind filing this request directly against https://github.com/beautify-web/js-beautify ?
