Chest boat texture layout is using the old chest uv layout

While porting some chest textures in a resource pack, I realized that the chest texture of the chest boat, besides it being a few pixels smaller per panel, it's using the old chest texture layout. 
In the images, the left chest layout is the current boat texture layout, that produces the front boat in the in-game screenshot, and the right chest layout (which matches the current chest entity layout) produces the chest in the back of the game screenshot.
