sunlei/zsh-ssh completion breaks zstyle

[lrnd1]

I have installed sunlei/zsh-ssh, however it conflicts with Z4H.

After some digging I realized that the issue comes from the plugin changing the bindkey to use it's own instead of z4h-fzf-complete.

zle -N fzf_complete_ssh
bindkey '^I' fzf_complete_ssh

Inside the function it also has a fallback option for ${fzf_ssh_default_completion:-expand-or-complete}.

fzf_complete_ssh() {
  local tokens cmd result selected_host
  setopt localoptions noshwordsplit noksh_arrays noposixbuiltins

  tokens=(${(z)LBUFFER})
  cmd=${tokens[1]}

  if [[ "$LBUFFER" =~ "^ *ssh$" ]]; then
    zle ${fzf_ssh_default_completion:-expand-or-complete}
  elif [[ "$cmd" == "ssh" ]]; then
    result=$(_ssh_host_list ${tokens[2, -1]})
    fuzzy_input="${LBUFFER#"$tokens[1] "}"

    if [ -z "$result" ]; then
      zle ${fzf_ssh_default_completion:-expand-or-complete}
      return
    fi

    if [ $(echo $result | wc -l) -eq 1 ]; then
      _set_lbuffer $result false
      zle reset-prompt
      # zle redisplay
      return
    fi

    result=$(_fzf_list_generator $result | fzf \
      --height 40% \
      --ansi \
      --border \
      --cycle \
      --info=inline \
      --header-lines=2 \
      --reverse \
      --prompt='SSH Remote > ' \
      --query=$fuzzy_input \
      --no-separator \
      --bind 'shift-tab:up,tab:down,bspace:backward-delete-char/eof' \
      --preview 'ssh -T -G $(cut -f 1 -d " " <<< {}) | grep -i -E "^User |^HostName |^Port |^ControlMaster |^ForwardAgent |^LocalForward |^IdentityFile |^RemoteForward |^ProxyCommand |^ProxyJump " | column -t' \
      --preview-window=right:40%
    )

    if [ -n "$result" ]; then
      _set_lbuffer $result true
      zle accept-line
    fi

    zle reset-prompt
    # zle redisplay

  # Fall back to default completion
  else
    zle ${fzf_ssh_default_completion:-expand-or-complete}
  fi
}

I placed the source after z4h init and added a variable fzf_ssh_default_completion="z4h-fzf-complete" before sourcing zsh-ssh.zsh so it would call z4h-fzf-complete whenever the command isn't ssh.
However, it still breaks the zstyle options, despite being loaded correctly, which I have no idea how to fix.

❯ zstyle -L ':z4h:fzf-complete'
zstyle :z4h:fzf-complete fzf-bindings tab:repeat
zstyle :z4h:fzf-complete recurse-dirs no

zstyle works even after sourcing zsh-ssh.zsh if I use z4h-fzf-complete but no matter what I try, it's ignored with fzf_complete_ssh
I have a low understanding of how zstyle works.
If anyone could point me to the right direction on how to troubleshoot or fix the issue, I would really appreciate it.
