Sort of.  There is some interaction with the suggest-key-bindings
feature.  On the first run, the mark stays active until the message with
the suggestion goes away, and only then gets deactivated.

    You can run the command ‘mark-test-run’ with M-x ma-t RET

If set suggest-key-bindings to nil, or type in exactly M-x ma-t RET,
then the mark is deactivated the first time too.

Yeah, I think it's the same issue.  If I include (setq
suggest-key-bindings nil) and (make-local-variable 'deactivate-mark)
then the mark stays active consistently.
