When a Trial Spawner or Vault gets set on fire (via Ominous Trial projectiles, dispenser traps, or other means), they still emit loot, causing it to burn and get lost. This isn't good especially for Ominous Trial Spawners, because sometimes you would be unable to put out the fire in time when finishing off the rest of the mobs a ways away from them.

Steps to Reproduce:
1. Set a Trial Spawner on fire at the top of the block
2. Kill all of the mobs that the Trial Spawner summons
OR
1. Set a Vault on fire at the top of the block
2. Unlock the vault with a key

Expected Results:
Trial Spawners/Vaults cannot be set on fire at the top of the block, OR they don't emit their loot while on fire.

Observed Results:
Trial Spawners/Vaults emit their loot while on fire, causing the loot to burn.
