This was fixed in July 2010, so eventually you won't need to do anything:

        * users/15217: Src/Zle/zle_main.c: use top-level status
        when redrawing prompt.

In the meantime, try this:

   function zle-keymap-select {
     local Q=$?
     (return $Q)
     zle reset-prompt

If your zsh is recent enough to have anonymous functions, you can replace
the subshell (return $Q) with (){ return $Q }.
