I expected to happen was, the soul sand makes me walk vary slow.

What actually happened was...:
In 1.16 pre-5, soul sand is pushing me around like water. I have tried restarting my launcher and it didn't work. I also tried restarting my whole computer. I also searched this bug up and theres nothing. So I made this bug report.

Steps to Reproduce:
1. Go to the nether.
2. Find soul sand
3. Walk in it and you might see it move you around
