Water drops dont work/reset the amount of blocks you're falling . 

*Issue:*I have a  water drop to my mob spawner which goes from y cords 66 to 12 . So i put a water source with signs three blocks above the point i fall and i used to take no fall damage before joining the beta maybe it worked in 1.14.0.2 I dont remember.

Visual Proof:

1.Fall from Top

2.Halfway Through Falling[Sorry because it is dark]

3.Almost reached

4.Dead

Steps To Reproduce

•  Dig a hole to bedrock
• Place water three blocks above the point where you should fall
• Go to gamemode s 

Result: You take fall damage and die

Expected: Water drops should reset the amount of blocks you're falling and thus you should not die with a big drop.
