/* Description of the test:
* With beacon.enabled=false, navigator.sendBeacon() must stay exposed and
* report success, but must not create a request. A content policy records
* every beacon channel and rejects it so that nothing reaches the network.
* The sentinel beacon, sent with the pref back on, is necessarily observed
* after the disabled one would have been, so seeing the sentinel proves the
* disabled beacon created no channel.
