Ability to walk through chests
If you place down a chest in, you have the ability to walk trough said chest. To visualize this, I created a short video:
html 5 Version(1mb)
gif Version(11mb)
So far I've only been able to recreate this in singleplayer creative mode and it appears that the orientation of the chest does not matter.
Edit: This issue is pretty inconsistent and it usually takes a few tries to pass through the chests.
Edit 2: Added the console output
