You are able to walk through fences when gravel or sand is placed above you.
Steps to Reproduce
Place fences 5 blocks long and 3 blocks high.
Walk to the middle of the fences. (Make sure you are up against the fence and facing it. See photo attached.)
Look up and place gravel or sand above you twice.
Look directly ahead and now you can walk through the fence that is in front of you!

I can confirm this for 0.14.0

Confirmed for 0.15.0. (Tested using Windows 10.)

I think this is caused by the fence's collision box expanding due it connecting to the gravel. When that happens hou are now inside the box and this means you can simply just exit the box by walking throuh the restof the way as if you were stuck in a block.
