So, the problem is that I made a slime entity that bounces like one, looks like one and is basically a perfect slime. But the slime attack component is broken, cause it doesn't deal damage to the player. On the contrary, if I used melee attack behaviour, the slime would stop rotating while bouncing. In fact, if I were to copy the slime entity behaviour in the official behaviour pack and add the slime runtime identifier it still would be broken.

What basically happens is that the slime stops rotating as soon as it acquires a target so it runs away from the target and won't start rotating again till it loses the target, this makes them kind of useless
