can't override subtitle track with local mpv.conf

[tastytea]

I sometimes use a directory-local mpv.conf (use-filedir-conf) to force a subtitle track, in this case the local mpv.conf contains sid=2. Without mpv-autosub it works but when the plugin is loaded the default (or the first?) track is always selected.

Is it possible to have the plugin respect the configuration?
