[MC-172573] Entities are not moved at all when between two opposing water streams

When you throw an item in between two opposite water currents, the item gets stuck there.

Also applies with armor stand and player

as you can see when the item is in the exact location with no momentum, it won't get pulled in either way, although it's not perfectly in the center.

dig a 1*4 trench, put water in two middle blocks, throw an item in the middle
