Hateforge - Gaining Maximum Rage in 1 hit does not trigger Hateforge effects

When gaining rage equal to or greater than your maximum rage, Hateforge's effects do not activate:

"Gain 3 random charges on reaching maximum Rage"
"Lose all Rage on reaching maximum Rage"

I found this by having a -9 maximum rage Hateforge (giving me 21 maximum rage), and having 21 rage on melee hit.

My maximum rage is listed as 21, and rage on hit is 21, yet when I hit an enemy, I get 21 rage which does not go away and I also don't get any charges. Subsequently hitting an enemy while at maximum rage also does not trigger Hateforge's effects - I have to wait for my rage to degen a bit and then hit an enemy for it to work.


Steps to reproduce:
1. Equip Hateforge with enough -max rage (ie. -9).
2. Equip jewels and passives with rage on melee hit equal to or greater than your maximum rage (ie. 21) (warrior passives, time-lost rubies with "Notables grant +1 rage on melee hit", regular rubies with +1 rage on melee hit)
3. Hit an enemy with a melee attack.

Ran into this too. Was cooking up a build... so sad.
