Filter device power management keyboard events?
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?
