Describe the bug when I try to add a xspf playlist to an existing xspf playlist it gives me an error when I try to play it.

To Reproduce Steps to reproduce the behavior:

1. I clicked the + to add a file, I chose an xspf playlist that contains references to other xspf playlists.
2. anything in the playlist that was not a xspf file played fine but if I choose an xspf file or tried to load one into the playlist it wont play.
3. I get the error exit code 2
4. /usr/bin/mpv --no-quiet --terminal --no-msg-color --input-ipc-server=/tmp/smplayer-mpv-e6e --msg-level=ffmpeg/demuxer=error --video-rotate=no --no-config --no-fs --hwdec=no --sub-auto=fuzzy --no-input-default-bindings --input-vo-keyboard=no --no-input-cursor --cursor-autohide=no --no-keepaspect --wid=186646559 --monitorpixelaspect=1 --osd-level=1 --osd-scale=1 --osd-bar-align-y=0.6 --sub-ass --embeddedfonts --sub-ass-line-spacing=0 --sub-scale=1 --sub-font=Arial --sub-color=#ffffffff --sub-shadow-color=#ff000000 --sub-border-color=#ff000000 --sub-border-size=0.75 --sub-shadow-offset=2.5 --sub-font-size=50 --sub-bold=no --sub-italic=no --sub-margin-y=8 --sub-margin-x=20 --sub-codepage=ISO-8859-1 --sub-pos=100 --volume=55 --cache=auto --screenshot-template=cap%F%p_%02n --screenshot-format=jpg --screenshot-directory=/home/user/Pictures/smplayer_screenshots --audio-pitch-correction=yes --volume-max=110 --term-playing-msg=MPV_VERSION=${=mpv-version:} INFO_VIDEO_WIDTH=${=width} INFO_VIDEO_HEIGHT=${=height} INFO_VIDEO_ASPECT=${=video-params/aspect} INFO_VIDEO_FPS=${=container-fps:${=fps}} INFO_VIDEO_FORMAT=${=video-format} INFO_VIDEO_CODEC=${=video-codec} INFO_DEMUX_ROTATION=${=track-list/0/demux-rotation} INFO_AUDIO_FORMAT=${=audio-codec-name} INFO_AUDIO_CODEC=${=audio-codec} INFO_AUDIO_RATE=${=audio-params/samplerate} INFO_AUDIO_NCH=${=audio-params/channel-count} INFO_LENGTH=${=duration:${=length}} INFO_DEMUXER=${=current-demuxer:${=demuxer}} INFO_SEEKABLE=${=seekable} INFO_TITLES=${=disc-titles} INFO_CHAPTERS=${=chapters} INFO_TRACKS_COUNT=${=track-list/count} METADATA_TITLE=${metadata/by-key/title:} METADATA_ARTIST=${metadata/by-key/artist:} METADATA_ALBUM=${metadata/by-key/album:} METADATA_GENRE=${metadata/by-key/genre:} METADATA_DATE=${metadata/by-key/date:} METADATA_TRACK=${metadata/by-key/track:} METADATA_COPYRIGHT=${metadata/by-key/copyright:} INFO_MEDIA_TITLE=${=media-title:} INFO_STREAM_PATH=${stream-path} --audio-client-name=SMPlayer --term-status-msg=STATUS: ${=time-pos} / ${=duration:${=length:0}} P: ${=pause} B: ${=paused-for-cache} I: ${=core-idle} VB: ${=video-bitrate:0} AB: ${=audio-bitrate:0} /somedir/somefile.xspf

Failed to recognize file format. Exiting... (Errors when loading file)

Expected behavior what should happen IMHO is it loads the xspf into the current playlist like it does on other players.
