 * 1. On WebKit browsers, a media query has to have at least one rule in order for `matchMedia`

 * 2. In some cases Blink browsers will stop firing the `matchMedia` listener if none of the rules
 * inside the `@media` match existing elements on the page. We work around it by having one rule
 * targeting the `body`. See https://github.com/angular/components/issues/23546.
