Slime and Magma Cube can still attack player during death animation

Slime and Magma Cube can still attack player during death animation.

How to Reproduce:

1. summon a Slime or Magma Cube.
2. set the game mode to survival.
3. Kill it closely.

You'll find that you got hurt by Slime or Magma Cube, althouth its health was 0.

In my opinion, dying Slime and Magma Cube shouldn't attack player, because they are already died.
