Smokers cannot be crafted using crimson or warped stems

In the new snapshot you're unable to make Smokers with the nether wood blocks. Is this something that was missed or are we going to be unable to make them?

What I expected to happen was...:
I am attempting to make a Smoker out of the new Nether Wood blocks.

What actually happened was...:
I was unable to create the Smoker

Steps to Reproduce:
1. Obtain a Furnace and Four Nether Logs
2. Attempt to make the Smoker

3. Observe that you are unable too.
