Particles created from Slimes do not account for the scale attribute

Expected Behaviour:

When changing the scale attribute of big slimes, their created particles should match their size, just like it does with players.

What happens instead:

The scale attribute does not affect the particle effects caused by slimes.

How to reproduce:

1. Summon a slime with with size 4

   summon slime ~ ~ ~ {Size:4}
   

1. Reduce its scale

   attribute @e[type=slime,sort=nearest,limit=1] generic.scale base set 0.1
   

1. You'll see that the slime will still generate a lot of particles.
