Describe the bug
A clear and concise description of what the bug is.

What is the block/entity this texture is affecting?
Orange Candle when Lit

There was Z fighting at the topside of the block. While I understand the topside is not commonly used, I have used it in my builds personally.

Furthermore, it seems there is a layer being rendered inside the block unnecessarily.

Screenshots
(I couldn't get a decent photo of the Z fighting but imagine the topside of the block has it lmao)

I am unable to reproduce any z-fighting, but I also see the unnessescary surface inside (ill remove it for the tiny performance improvement but I dont think its causing any issues beyond that)
