Foxes holding the Mace do not deal any more damage when doing a pounce attack than when doing a normal attack

The Bug:

Foxes holding a Mace and attacking chickens deal 8 damage, whether they dive from a high height or attack normally.

To Reproduce:

1. Drop a Mace on a Fox. The Fox will pick it up.

2. Spawn a Chicken, Rabbit, or another mob that Foxes will naturally attack. Give it a large amount of health using attributes.

3. Using /data, observe the amount of damage the prey animal takes from the Fox holding the mace. Even when the Fox does a pounce attack, taking it nearly 4 blocks into the air before falling back onto the enemy, it still only deals the base 8 damage given by the Mace without taking into account damage added by fall distance.
