fzf-tab: [BUG] Pictures previews not working with chafa and `-f kitty`

I can make sure:

• I am using the latest version of fzf-tab
• this is the minimal zshrc which can reproduce this bug
• fzf-tab is loaded after compinit
• fzf-tab is loaded after plugins which will wrap <kbd>Tab</kbd>, like junegunn/fzf/completion.zsh
• fzf-tab is loaded before zsh-autosuggestions, zsh-syntax-highlighting and fast-syntax-highlighting.

Describe the bug

I followed the wiki for Previews - show file contents.

It works just fine with the following script (taken from the wiki too, slightly modified):

#! /usr/bin/env bash

has_cmd() { command -v "$1" >/dev/null 2>&1 ; }

MIME="$(file -bL --mime-type "$1")"
CATEGORY="${MIME%%/*}"
KIND="${MIME##*/}"

if [[ -d "$1" ]]; then
    has_cmd exa && exa -a --color=always -l -g --git --group-directories-first --icons "$1"
    has_cmd lsd && lsd -al --color=always --icon=always "$1"
elif [[ "$CATEGORY" == "image" ]]; then
    has_cmd chafa && chafa "$1"
    has_cmd exiftool && exiftool "$1"
elif [[ "$CATEGORY" == "text" ]]; then
    has_cmd bat && bat --color=always --line-range :200 "$1"
elif [[ "$CATEGORY" == "video" ]]; then
    has_cmd mediainfo && mediainfo "$1"
else
    lesspipe.sh "$1" | bat --color=always --line-range :200
fi

Relevant part of my fzf-tab config:

zstyle ':fzf-tab:complete:*:*' fzf-preview 'less ${(Q)realpath}'
zstyle ':fzf-tab:complete:*:*' fzf-flags --height=100% --preview-window=right:wrap
zstyle ':fzf-tab:complete:*:options' fzf-preview
zstyle ':fzf-tab:complete:*:argument-1' fzf-preview
export LESSOPEN='|/path/to/lessfilter.sh %s'

However, pictures previews aren’t working with chafa when using kitty terminal (and default preview format).

From man chafa:

       -f, --format format
           Set output format; one of [iterm, kitty, sixels, symbols]. The default is iterm, kitty or sixels if the connected terminal
           supports one of these, falling back to symbols ("ANSI art") otherwise.

Since I’m using kitty, running chafa without any argument defaults to -f kitty, which doesn’t seem to work:

It works fine if run directly in terminal with:

❯ chafa 01.jpg

If using

chafa -f symbols "$1"

in the script, it works too, but the preview quality is very bad of course:

Environment:

• OS: Gentoo

❯  zsh --version
zsh 5.9 (x86_64-pc-linux-gnu)

❯  kitty --version
kitty 0.25.2 created by Kovid Goyal

❯  chafa --version
Chafa version 1.12.3

Am I missing something or is this a fzf limitation?

Thanks.
