soul sand pushing player off of it

Put the summary of the bug you're having here

What I expected to happen was...:
Soul sand should just slow movement and not move the player without any key presses

What actually happened was...:
the soul sand pushes the player off when there is a drop, this also happens with tilled soil. I would expect the same to happen to stacked snow but this doesn't happen with stacked snow

Steps to Reproduce:
1. stand on soul sand
