Missing theme tag

[edalzell]

Tag is in the code, looks the same as in v2, but not in the tags listing.

I wonder if we should leave it out of the docs. We don't have themes anymore. I don't know if it's really that helpful. Happy to be told otherwise. I think it's mostly just there for backwards compatibility.

Agreed. That's exactly why it's not documented.
