Slimes have no attack cooldown, resulting in the player taking numerous hits repeatedly depleting their health far quicker than other mobs with normal attack cooldowns.

Steps to Reproduce:

1. Modify the player's knockback resistance:

   /attribute @p minecraft:generic.knockback_resistance base set 100
   

2. Give the player regeneration:

   /effect give @p minecraft:regeneration infinite 255 true
   

3. Summon a slime with a size large enough to attack you

   /summon minecraft:slime ~ ~ ~ {Size:3}
   

4. Walk up next to the slime

Observed Behavior:

The player is attacked in rapid succession, with no delay in between each attack.

Expected Behavior:

The player would be some invulnerability before taking damage again, like other mobs.
