Loss of a trident

Hello, 30min ago I was on a small server with my friends (Server.pro hosting) and I was playing with the Trident (Impaling V, Channeling, Mending, Unbreaking 3, Loyalty 3) on a Thunderstorm, and because I had a Channeling enchantment I wondered what would happen if I kill myself using the trident, apparently that was a bad idea... When I died, my trident didn't even get back to me neither was it on the ground at the place where I died. I just wanted to know if that's a bug or is that a feature that it can't be returned when you kill yourself using it.
