Additional Information

Found this when play with my external lyric OSD app, and lyric jitters backwards repeatedly, so I checked playerctl position

I was able to reproduce this issue

#!/env/bin/fish

# loop 1000 times
for i in (seq 1 1000)
    echo (playerctl position)
    sleep 0.001
end

1009.028044
1009.028043

While looking for a different but i came across this issue. For me the position just keeps adding up untill i skip a song, so sometimes position would be 40 mins big etc. Might create seperate issue for that
