Good catch.

If one of the windows has focus, its point gets reset to the message
containing point before the refresh call (the standard notmuch-show
current refresh behaviour). The windows which don't have focus get reset
to the first message.

We want to make all windows showing a buffer get adjusted, right?
I can add this to v2.

Yes, this is much clearer, I will update in v2.
