Problem / Steps to reproduce

Is there a way to inherit the STDIN in zle widget mode? For example here fzf won't properly work since it doesn't inherit the files in ZLE mode.

y() {
  fzf
  zle reset-prompt
}

zle -N y
bindkey '^Y' y

For details see the resulting problem dicussed in yazi: sxyazi/yazi#3503

Using https://github.com/junegunn/fzf/blob/master/shell/key-bindings.zsh#L77 as a reference, I'd try:

y() {
  fzf < /dev/tty
  zle reset-prompt
}

zle -N y
bindkey '^Y' y

Given that by default stdin is set to /dev/null, I think fzf detects that. The above should route user input into fzf in a detectable way that you can provide input for. Might be able to do similar with /dev/stdin, but not sure that has the behavior you want.
