* Creates an empty stylesheet that is used to work around browser inconsistencies related to

* 1. On WebKit browsers, a media query has to have at least one rule in order for `matchMedia`
* to fire. We work around it by declaring a dummy stylesheet with a `@media` declaration.
* 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.
