Loyalty trident rubber-bands around players who have used Elytra
Gliding with an Elytra causes the trident with the Loyalty enchantment to not return to the user correctly
The only way to fix this from what I know of in to use a trident with the riptide Enchantment

How to reproduce it
1. Equip and glide with elytra
2. Land and then throw the trident with the loyalty enchantment
If reproduced correctly, the trident will try to reach the player, but cannot and will float around the player's head until it touches your body
