I prepared a small registry json:

Expected behavior: Smashing a light blue stained glass block yields a diamond, and smashing a red stained glass block yields a piece of redstone dust.
Actual behavior: Smashing a white stained glass block yields a piece of redstone dust. No other stained glass blocks affected. Reversing the order of the recipes will cause the white glass to yield a diamond instead.
