Incorrect Legacy Block Mappings for Short and Tall Grass

[Axionize]

To start off with some definitions. Short grass is grass that looks like this.

Tall grass is grass that looks like this.

StateTypes.TALL_GRASS is correctly returned for Tall Grass on 1.21 and StateTypes.SHORT_GRASS is correctly returned for Short Grass on 1.21.

The StateTypes.TALL_GRASS is returned for Short Grass on 1.8 and StateTypes.PEONY is returned for Tall Grass on 1.8 Is this intentional? Short grass is called "tallgrass" in 1.8 so does this inconsistency exist to accommodate legacy Minecraft's actual block names? If so, what's the intended way to deal with these blocks consistently across versions?
