Named Blocks are Normal when Dropped

So, I had a jukebox. It was named "2013 Special Radio" because I am very random. I placed it on the floor to play music for my cats for some reason, and when I picked it back up to put it away, it was named plain old "Jukebox".

How To Recreate:

1. Name a block.
2. Place it down somewhere.
3. Pick it back up.
4. It will lose its name.

I didn't see any duplicates of this!
