Animated textures in resource packs aren't animated in advancement icons

While having an animated resource pack enabled, The advancement section of your pause menu does not animate the items/blocks in it's icons and tabs. for example, the advancement "Hot stuff" has a lava bucket and this item is animated in the game. but whenever the advancement section is open, the icon for any animated item including the lava bucket is frozen in its last frame before the game was paused.
