I've got a couple of bugs I've encountered regarding the trident.
1. I've noticed that when using the trident it's not possible to draw back if your looking at a mobspawner or endframe. Or really most any block that you'd have insert items into/ui interaction with Ex: being crouched and trying to throw it at an Anvil, Crafting Table, Lever, etc. Note that this is only an issue if the object your aiming at is within a reachable distance and can be highlighted.
2. Throwing the trident through the Nether Portal upon being transferred either to or from the nether causes you to lose your trident, which is saddening lol.
And yes all of these occurred while using the loyalty enchantment.
