Attribute req not disabling item/skill? Bug 1,410,804,474

OK I _think_ this is a bug; not sure exactly what order of operations etc, but I had just replaced a belt with STR with the Stygian Vise without, to fix INT requirements disabling Hyrri's Ire due to skill gem. So this isn't generally broken on my char afaict.

You can see Anger is equipped in the Head slot and requires 98 int, and I'm a few short. However Anger is clearly running and the head slot is not disabled, though I think its effects are not being applied.

Then shouldn't this be reflected in the effective stat requirement displayed?
