Ender Chests showing Xmas Skin in Xmas

This might be intended but it is not in the wiki so I decided to report. I wanted to see the Christmas textures for the chests, so I changed the date on the computer to 24th December, as the wiki states chests will show their Christmas textures from 24th to 26th December. Everything fine, the chests actually presented like in Christmas, but the Ender Chest changed textures aswell. I got super confused because you cannot really spot the differente between an Ender and a normal chest then, except for the ender particles. As shown in the screenshot, both chests look the same, except for the particles above the right one which is the ender chest.
