Boat With Chest doesn't have Christmas texture

Hi.

I was testing a texture pack in my world, and I noticed that the chests on the Boats With Chest doesn't have the Christmas texture as the other chests.

How to replicate (Only during Christmas):
1.- Place a Chest in the world.
2.- Place a Boat With Chest in the world.
3.- You'll see that the chests have different textures
