zsh: Extra space gets inserted when aborting <Space>+<Tab> fzf window

[ferdinandrau]

Hi, thanks for making this great tool.

When using it under Zsh I've encountered a small annoyance: When closing the fzf completion menu opened with tab, a space character gets inserted after however many trailing spaces there already where. So when you open and close the menu a bunch of times, each time a space gets added and you end up with that number of trailing spaces (+1, obviously). This does not happen when doing <Space>+<Ctrl-D>, which i have mapped to the list-choices ZLE widget (standard mapping in the vi insert mode of Zsh).

I can reproduce this with a minimal .zshrc on Zsh 5.9 (macOS, left out some irrelevant parts):

zstyle ':completion:*' menu select
zstyle ':completion:*' completer _extensions _complete _approximate
zstyle ':completion:*' matcher-list '' m:{a-zA-Z}={A-Za-z} 'r:|[._-]=* r:|=*' 'l:|=* r:|=*'
zstyle ':completion:*' squeeze-slashes true
zstyle ':completion:*' complete-options true
zstyle ':completion:*' use-cache true
zstyle ':completion:*' cache-path "$ZSH_CACHE_DIR/compcache-$ZSH_VERSION"

autoload -Uz compinit && compinit -d "$ZSH_CACHE_DIR/compdump-$ZSH_VERSION"

eval "$(zoxide init zsh --cmd cd)"

I would say this behavior is not really desirable and probably a bug because exiting the menu should not alter what has been typed at all.
