Armor equip sound only on right click

The new armor equip sounds is only played when right clicking the item. When dragging or shifting the item into the armor slot the sound doesn't play. (Same for the elytra.)

I'm not sure if this is a bug, but I think it's not making that much sense only playing the sound on right click. Please fix it.

BTW, an unequip sound (the equip sound with lower/higher pitch) would be cool too ..
