Polymath with Traps

It is my understanding that Polymath's Life/ES/Mana recovery on kill should work with traps, but I'm not seeing this actually work. I believe I'm getting the increased damage, but whenever my traps kill an enemy, each enemy killed should give my Lvl 54 Trickster 47 Life, 28 Mana, and 8 ES. None of these occur. I tested this at half health and killed a pack of 8-12 white mobs. This should have instantly put me at or close to full health, but I got nothing except my normal Life and Mana regen. I know that traps can't leech, but I thought traps counted kills for the character in this instance. If this is supposed to work similarly to leech, then can we get a clarification update to say so?

My understanding was that, similar to minions, hits that kill would be considered to be the trap's kill, while dots that kill would be considered your kill.

It seems to hold true in testing with Fire Trap and Blood Rage, refreshing the buff and generating Frenzy charges when enemies die to the burning ground. Testing with Lightning Trap instead, Blood Rage's buff never refreshed on kill.

Thanks, I just tested this with Fire Trap and it works as you described. So basically, unless I can force the kill with a DoT, Polymath is just a damage boost for traps? Seems kind of sad to not be able to use the full power of the Ascendancy node when Headhunter works just fine with traps and uses the same wording.
