 Firefox detects power management events and propogates them as keyboard
 events, so a website knows when a device wakes up from sleep. Although
 there are many ways a website can detect a client disappears and/or goes
 offline, it seems worse that a web server can be notified when a device
 wakes up from sleep (or other related events). Should these be filtered
 before they reach the web api?
