Texture minecraft:block/sniffer_egg_slightly_cracked with size 40x32 limits mip level from 4 to 3

Upon starting the game or reloading resource packs, the message Texture minecraft:block/sniffer_egg_slightly_cracked with size 40x32 limits mip level from 4 to 3 is logged. I don't know if this actually limits the mipmap size (which would limit the size to 3 instead of the current 4) or it's just a logging error.
