Subject: [PATCH] never trigger edges during the cooldown

regardless of whether the pushback is forced down or the user
has deactivated it or whatever. The edge is waiting from previous
activation and we need to prevent immediate reactivation since that
may cause duplicate action and unwanted state toggles
