Centaur's passive, Return, is able to trigger even after Centaur Warrunner died. Projectiles which already fly towards him will trigger it, damaging their source.

1. Get attacked by a ranged hero with fast attack speed
2. Die to the attacks
3. Observe Return's behavior against the projectiles which were launched before your death, but hit you after the death

Result: These projectiles trigger Return, and the enemy takes damage from it.

Expected: Once dead, Return should stop triggering.
