When using the BumpOffset node, it will produce incorrect resultsi if the Texture Coordinate Index is not 0.
Found in 4.20 CL# 4369336. 4.21 CL# 4613538, 4.22 CL# 4751672
It appears the BumpOffset node is still partially relying on Coordinate Index 0
Incorrect Behavior would not occur when the Coordinate index is above 0
