Boats are immediately sunken if there is a string on the surface of the water

The bug

I would imagine that this is not indented behavior, but this is definitely interesting for sure. 
Basically, if there is a string on the surface of the water above a magma block, boats are immediately sunken when going over it instead of taking a few seconds to go down.

How to reproduce
