With a 2 layer high snow (0.125 +y) above the slime, it always creates the ground detection bug. if you spawn a villager and push him off of the snow layers and onto the slime it always creates the villager gui bug. Therefor the Villager GUI Bug is indeed directly related to this.
For Example: if a villager falls from 1.125 y (1 block + 2 layers of snow) to 1 y (Onto slime) the GUI doesn't work correctly.
So in effect, the villager GUI bug is actually just this bug in relation to villagers.
Yes indeed, I Forgot to note that. I'm Running Further test to figure out some of the exact heights that create the ground detection bug. I will inform you when i have new information
