Yes, it still occurs in Preview/Beta and or 1.19.50.
It’s not really a parity issue because it’s on both Java and Bedrock Edition. But I still think it is a mistaken texture for the pillager, the vindicator, and the illusioner because both sides of their heads should be the same like the evoker’s head. Don’t worry about the one in Minecraft Dungeons.
It might be a bug because one time, Jens Bergensten, the lead creative designer of Mojang said that there are some parity bugs. Plus, the developers wanted Minecraft Java and Bedrock Edition to have the same features.
