Put the summary of the bug you're having here

What I expected to happen was...:
So I currently built a small bee farm, and I did not like the way a campfire looked directly underneath the beehive, so i made a little redstone and sticky piston configuration that pulls back a block to release the flame so I can collect the honey without upsetting the bees and puts the block back once I step off the button.

What actually happened was...:
It works well, but there is the smoke particle effect that comes off the campfires goes through the sticky pistoned block. Its primarily a visual bug, but still annoying to see smoke particles poking through the block.

Steps to Reproduce:
1. extend a sticky piston with any block above it,
2. Place campfire underneath extended block
3. see the smoke particle effects phase through extended block.
