When You Push The ^ (Move Forward) Arrow 2 Times While In 1 block of Water of less. You Will Start Swimming, But It Won't Work And You Stay Standing.

What I Was Expecting Was:

You Can Still Swim In shallow water

What Happened Was: 

i cannot swim in water that is 1 block deep or less

Steps To Reproduce

1. Go Into Water That Is 1 Block Deep or Less

2. Push The ^ (Forward Button) While In The Sallow Water

3. Here Is The Issue: You Will Just Run Like You Are On Land And Not Swim In The Water.
