The Bug:
Glass blocks held by endermen are visually opaque.
Steps to Reproduce:
Disable mob spawning.
Run command: /kill @e[type=enderman]
Place down an oak boat.
Stand on the boat’s center, then run this command: /summon enderman
Ensure the enderman is sitting in the boat. If the enderman happens to teleport away immediately, redo step 2, then redo step 4, and then proceed to step 5 again. Otherwise proceed to step 6.
Run this command: /replaceitem entity @n[type=enderman] slot.weapon.mainhand 0 glass 1
Now look at the enderman’s attached block. Notice the glass looks opaque as the enderman’s held block.
Expected Result:
Glass held by enderman has to render transparent to match Java. (For expectation, see Java_behavior.png)
Observed Result:
Glass held by enderman renders opaque. (For observation, see Bedrock_behavior.jpeg)
