MCPE-41428 was fixed, giving small mushrooms, mushroom blocks and mushroom stems unique names. Despite this, the mushroom block with the pores texture on every face - which is available in Creative Mode - still uses the generic "Mushroom" name. Since it's a supported mushroom block variant, available straight from the creative inventory without any weird command, it should be changed to something like "Mushroom Pores" or even just "Mushroom Block".
