Yes. After it downloads, it still says "Unknown key KEYID or unsupported
algorithm". I would be confused by the unsupported algorithm - it is
just an RSA/RSA key, newly created. This has also happened for other
signed messages - it downloads the key, but still says it doesn't know
the key (and this persists across restarts of emacs).

That works, and it shows the key there.

One thing I forgot to mention - I have notmuch running on a remote
server through ssh. I don't really imagine this would be an issue, but
maybe? (I also have the library installed locally, for emacs).
