Unlike Bedrock Edition, feeding torchflower seeds to a sniffer that has less than full health will not heal it.
Steps to Reproduce:
Spawn a sniffer
Attack it until its hp is 1
Feed torchflower seeds to it
Attack it again with low damage
Observed Results:
The sniffer was killed, meaning that feeding didn't heal it.
Expected Results:
Sniffers should be healed, so it will not be killed.
Summon a sniffer with low health for easier testing (can be killed in one hit):
