Preview-tui setting $NNN_PREVIEWVIDEO incorrectly?

[fuzxi]

Hey, I'm running Artix and using nnn on wezterm (no tmux) with mpv installed and was unable to see video and gif previews in preview-tui. Uninstalling mpv would show gif previews as ImageMagick is installed and apparently working. mpv --vo=help lists sixel as an available video output.

I dug around a little and was able to fix it by changing line 157 of $XDG_CONFIG_HOME/nnn/plugins/preview-tui from
exists mpv && ENVVARS+=("NNN_PREVIEWVIDEO=kitty")
to
exists mpv && ENVVARS+=("NNN_PREVIEWVIDEO=sixel")
and now video and gif previews work perfectly.

Was this an issue with my setup or is it an issue with the plugin? It seems odd to set kitty as the preview backend for a non-kitty terminal but I wasn't sure if I should open a bug report.
