This might be a clone of MC-161896, though I'm not entirely sure.
The bug
I was messing around with honey blocks making items fall slower when a honey block item fell through the honey block and caused a visual glitch. It appears the outer cube of the honey blocks cancel out allowing you to see through them like there is only one layer there.
Steps to reproduce
Place a honey block
Throw a honey block in front of the placed honey block
--> ❌ See visual glitch
