Variated textures do not apply overlay tint from colormaps

In an attempt to add variations to the “grass_side” texture, I added the following to the “terrain_texture.json”:

"grass_side": {
			"textures":{
				"variations": [
                	{ "path": "textures/blocks/grass_side0", "weight": 50 },
					{ "path": "textures/blocks/grass_side1", "weight": 25 },
					{ "path": "textures/blocks/grass_side2", "weight": 25 }
				]
			}
		}

I expected the grass overlay, which was defined correctly using opacity and grey scale , to be tinted via the grass colormap, however the grass portion of the texture remained greyscale. Notably, the grass could still be tinted manually using the “overlay_color” component but getting the grass side texture to follow the biome dependent tint of the grass colormap was the desired behavior.
