Confirmed for 1.14.3. The pillagers get confused by landforms and don't try to get out of the water when pathfinding in raids (they prioritize pathfinding in water over land even in non waterlogged blocks).

It's also worth noting that Patrols do not move at all unless the player is within range and/or hits the pillager patrol with a bow or trident. It might deserve its own bug report but is related to this bug.
