Resonating Shrine Not Triggering on Self-Hit?

Hello,

Using the new belt to grant the Resonating Shrine effect, I've noticed that it doesn't seem to count self-hits as hits. The wording on the Resonating Shrine buff is:

You have a chance to gain a Power, Frenzy, or Endurance Charge on Hit and on Kill, and have higher maximum Power, Frenzy and Endurance Charge count.

The specific effects from the wiki are:
20% chance to gain a Power, Frenzy or Endurance Charge on Hit
60% chance to gain a Power, Frenzy or Endurance Charge on Kill
+1 to maximum Power Charges
+1 to maximum Frenzy Charges
+1 to maximum Endurance Charges


I was using the Inexorable node which says "25% chance to gain an Endurance Charge when you are Hit" and Scold's Bridle to generate Endurance charges, and expected the same interaction to work with the Resonating Shrine since the shrine doesn't specify you have to hit something else to gain the charge on hit.

Is this a bug or intended behavior?
