Snowy Grass bug (was thought to be removed in 1.16 updates)

I created a new world on hardcore minecraft java edition 26.2 and i made a bed, i was in a snowy biome and i put the bed on the snowy grass then i looked under the bed and.. one of the blocks had the normal taiga grass texture but the other one was the snowy grass u only could accsess with the debug stick. Expected result: two normall grass blocks under the bed (in the snowybiome) Actual result: In the snowy biome when placed ontop of 2 snowy grass blocks, under the bed is a bugged snowy grass texture and a normall grass texture grassblocks.
