We need to check full-screen-api.unprefix.enabled pref when parsing :fullscreen pseudo-class, otherwise we are unintentionally shipping :fullscreen selector. Also note that, we want :fullscreen to be available in user agent sheet unconditionally, so we would need to do something like bug 1375374. There is currently no test checking this. We should add test to file_fullscreen-unprefixed-disabled-inner.html to ensure we don't regress it.
