Frogs don't de-aggro on slimes or magma cubes when put on the same team

I was messing with frogs when I had noticed that they were going to eat the small slimes and magmacubes, even after I put them on the same team.

To repeat this, summon a frog and a small slime/magmacube and put them on the same team before the frog eats it. The frog will still go after and chase the slime/magmacube even though they are on the same team, unlike other mobs that de-aggro when they are put on the same team.

In the image, I had summoned a slime and magmacube with a high resistance level so they couldn't be eaten.
