Old Boat Physics Causing Client Side Problems

While we were playing on the 20w22a Minecraft Snapshot (Running a Vanilla Server downloaded from the Minecraft Website), we found that when riding a boat off a ledge made of path block, it would cause major client side visual artifacts, then break the boat (returning sticks and wood, something that I thought had been removed from code), and caused more client side issues (like a disappearing hand and major rubber banding/lag). This was recreated in a plains biome in a Village.
