Chiseled copper texture has wrong lighting direction

 The dents in the chiseled copper texture(marked black on the image) use top right lighting, despite all other minecraft blocks using top left lighting (like diamond block, bamboo_top)

1 is how it is in 1.20.4
2 is how it would look like if it used a top left lighting direction

 

 

this issue applies to all the oxidised states as well
