What you want is not theoretically possible as far as I know.
Combining emojis is optional according to the specs, and zsh has no
way of knowing if a terminal will combine two particular emoji in a
zwj sequence, and thus has no idea how wide the sequence of characters
will be or when the terminal will start drawing on a new line.
