Trident dropped from Trial Chamber chest in Minecraft 1.21.8 (vanilla survival)

While playing on Minecraft Java Edition 1.21.8 (vanilla survival), I opened a chest inside a Trial Chamber and a trident dropped out of it.

I was not using any datapacks, mods or plugins. I recorded the moment

As far as I know, tridents are not listed in the loot tables for Trial Chambers, only dropped by drowned mobs. This may be a bug or an undocumented loot table change.

Steps to Reproduce:

1. Enter a Trial Chamber.

2. Loot chests.

3. Trident unexpectedly appears from chest.

idk if its a bug or not chatgpt said it is
