And it should disappear, so that's the bug?  What command does that
"Cancel" menu run?

message-dont-send is return-action, which is documented as

---
RETURN-ACTION, if non-nil, is an action for returning to the
caller.  It has the form (FUNCTION . ARGS).  The function is
called after the mail has been sent or put aside, and the mail
buffer buried.

message-kill-buffer isn't what's meant by return-action in the
compose-mail interface, I think?
