"history -0" works in ksh, why doesn't "history -0" work in zsh?

Why does ksh history -0 (last command which is the history command itself) work, yet zsh it fails (only history -1 avail on my zsh). I tried zsh -f to use default options and it still fails. I'm using ksh version Version AJM 93u+ 2012-08-01 and Zsh v5.9 on MacOS. This question is about the history command and not preexec() to get the current command.
