Shulker Box Does not change colour when displayed in recipie

What I expected to happen was for the result of the shulker box within the recipie to change colour to the chosen dye.

What actually happened was the colour of the shulker box stayed as the default colour

I went in acraftign table placedashulker box in 1 crafting space and a coloured dye in anouther and or tough the shulker box appeared asa craftable item the colour remained the same.

Steps to Reproduce:
1. Place a crafting table down and click on it
2. put a shulker box in any avilable crafting space
3. Place any coloured dye in anouther avilable crafting space
