Boats that are Invulnerable can break when driving into the coast

What I noticed:
I summoned a Boat with the Invulnerable Tag set to true into the coast and it broke. The Invulnerable Tag should protect it from any damage at all, so it's definitely a bug.

How to recreate:
Do /summon Boat ~ ~ ~

over a river.
Get in the boat.
Drive fast to the riverside.
The boat will break.

Why this bug is annoying:
That Boats break that quickly anyways is already annoying, so I tried to create a commandblock module that I can use in my world that sets the Invulnerable Tag for any Boats with a player in it to true and for Boats without a player to false to be able to actually use boats. Due to this bug, tít doesn't work. Annoying as hell.
