The user then logs in to the web app (via KC) and then logs out of the web
app (via KC).  Should the mobile refresh token then be able to successfully
refresh the mobile JWT access token against KC, or does the web logout
'invalidate' the mobile refresh token?

Logout only invalidates one session. Since you have a mobile app with
direct grant and a separate web app they have separate sessions.

All sessions except the session changing the password are logged out. So
the mobile refresh token should be invalid.

Yes/no. If you use an embedded webview it has its own cookies and doesn't
have access to the system browser cookies. So there's two separate
sessions. I'd still use webview though and not direct grant. A much better
option is to use an embedded system browser tab as it actually allows
having one session between multiple mobile apps and system browser. I've
got no clue how to do that though, I just read that's the proper way to do
it.
