Every block that doesn't emit light must be shaded, but some aren't.
Affected blocks:

• The blocks listed below don't emit light, so they should be shaded (inventory only):
  • Decorated Pot
  • All mob heads/skulls
  • All dripleaves
  • All banners
• The blocks listed below are shaded from the wrong direction (left side of the block instead of the right side):
  • Heavy Core
  • Stonecutter
  • Composter
  • Lectern
  • Grindstone
  • All anvils
  • All sculk sensors (emit light level of 1)
  • Sculk Shrieker
  • End Portal Frame (emits light level of 1)
  • All azaleas
  • Mangrove Roots
  • Scaffolding
• For comparison:
  • Bedrock Edition:
    
  • Java Edition:
    
• Additionally, the conduit emits light, so it shouldn't be shaded when dropped:
  

Steps to reproduce:

1. Open each of the attached worlds in their respective editions
2. Compare the shading of the items in the chests
3. In the Bedrock world, look at the shading of the dropped conduit

Observed result:
The shading is inconsistent across editions and sometimes outright missing in Bedrock Edition where it should be present. Dropped conduits are shaded despite the fact that they emit light.

Expected result:
The shading is consistent across editions and present where necessary in Bedrock Edition. Dropped conduits are not shaded.
