Silk Touched Mushroom Block

Please note that I searched before posting here, and almost all of the posts were from years ago, or addressed the opposite of what I’m asking.

Will mushroom blocks be fixed, so that when you harvest them with Silk Touch, you get the mushroom texture on all sides? I noticed when watching one of Xisumavoid’s videos, that Java edition still has this. Is this a bug or an international feature? (Really hoping it’s just a bug)
