You have SHARE_HISTORY on. It's not on by default.

Why not give a try to some minimal defauts?

  mkdir -p /tmp/zsh
  touch /tmp/zsh/.zshrc
  ZDOTDIR=/tmp/zsh HISTFILE=/tmp/zsh/.history SAVEHIST=30 zsh

It seems nobody knows what vanilla zsh actually does.

Quite easy:

  fc -p

It creates a new history stack (no $HISTFILE). To return to the previous one:

  fc -P

Cheers.
