Actually, that's an accident.
"zle -M" *simply* prints a message. It doesn't interact with
the normal editing buffer at all (which is the thing to which
POSTDISPLAY is appended). So if you're seeing it it's because it's
not overridden by the message.
It's worth scanning the zshzle manual to see if you're doing something
that might be better dealt with by Zle -R, which does a normal
redisplay with an optional message --- this is commonly the case
when within widgets.
