Is Iron grasp suppose to be like this with heroic tragedy?

I wanted to make a strength-stacker centered around Iron grasp. Iron will and Iron grip (two keystones granted by IronGrasp) make strength not give life anymore but give 1% increased projectile attack and spell damage per 2 strength. I wanted to use the heroic tragedy keystone circular teachings which changes the strength inherent bonus to be 1% increased energy shield per 2 strength to get around the Iron grasp downside. However, when I allocate the keystone, I lose the spell/projectile attack damage. Is this intentional? It doesn't make sense to me why this would work because I'm pretty sure downsides to keystone are design to be invalidated in cleaver ways like this and I'm pretty sure this kind of interaction works in poe 1. But if this is intentional then this unique will probably never see the light of day (at least from me).

Okay, see I wouldn't be so mad about this if the bonuses from Iron Grip and Iron Will were actually being treated like inherent bonuses and being doubled by Gemling's Enhanced Effectiveness. It should work with one of these two setups but apparently works with neither...
