At first I thought the example has the same problem, but I was
wrong. I just did some more research, and it seems, that storing
custom metadata actually works if you have it *only* in stage 3. My form
stores metadata in stage 1 *and* stage 2. As soon as metadata is
stored to extras in stage 1, nothing gets stored in stage 3.

Can anyone confirm this? I'd then report this as an issue.
