This is a internal-only syntax for guarding rules from a boolean
preference. Nothing causes @supports rules to be re-evaluated except
html.css registered in Part 2.
This is needed for rendering the disclosure triangle of the
summary element by using "display: list-item".
Usage example:
@supports -moz-bool-pref("dom.details_element.enabled") {
/* css rules */
}
