Non-living entities such as projectiles (arrows, snowballs, eggs, etc.), boats, minecarts, or dropped items cannot be extinguished by splash water bottles, unlike living entities such as the player. Water sources can extinguish them as expected, but splash water bottles cannot.

Steps to Reproduce:

1. Summon one of the following entities:

   /summon minecraft:item ~2 ~ ~2 {Item:{id:"minecraft:stone"},Fire:9999,Health:999}
   /summon minecraft:boat ~2 ~ ~2 {Fire:9999,Health:999}
   /summon minecraft:trident ~2 ~ ~2 {Fire:9999,Health:999}
   /summon minecraft:arrow ~2 ~ ~2 {Fire:9999,Health:999}
   /summon minecraft:spectral_arrow ~2 ~ ~2 {Fire:9999,Health:999}
   

Observed Behavior:

None of the listed entities will be extinguished by the water bottle.

Expected Behavior:

The entities would be extinguished, just as living entities are.

Notes:

1. When testing on projectiles, make sure they are not suspended in air, as splash water bottles do not collide with them.
