See title text.
Warpath lets you specialize into a node called Winds of Justice, which makes it cast smite every second on a nearby target.
Smite lets you specialize into a node called Descend that lets you teleport to a target you smited, but adds a cooldown. It also says in the ALT Text that it will not work with a traversal skill (neither be triggered by it, nor can be used while a different traversal skill is being used, nor can it come off cooldown while another traversal is being used).
Warpath is NOT tagged as a Traversal skill. It only has a movement tag. Thus, there is no suggestion in game that warpath with Winds of Justice triggering smite shouldn’t also trigger smite’s Descend and teleport you to your target. (Think flickerstrike from POE, while warpath whirling around).
This is either just bugged in game, or you need to change Smite’s Descend node to expressly say it wont be triggered by MOVEMENT skills as well as Traveral skills. And that’s a huge bummer. Let me flicker strike, damnit.
