Crying Obsidian uses its new texture even when using the Classic Textures RP, while in Java's Programmer Art it uses its old texture.

You might think that Bedrock never had the old Crying Obsidian, but its texture was in the game for nearly a year, being added in Pocket 0.1.0 Alpha and removed in Pocket 0.2.0 Alpha.

To reproduce this issue, simply enable the Classic Textures RP and place a block of Crying Obbi, and notice the texture.
