Extension doesn't update when using MPD only

I think I've ran into the same problem as described here.

I don't see any of the track or album update. I ran mpDris2 -d from my terminal (debug-mode) and I could see mpDris2 notifyes me that it's updating the current song info etc.

More Info:

The buttons are working great, they do everything they are supposed to do.
The time indicator is stuck after the 1st song is finished at the end of the time bar. It shows the time that have been through since the 1st song started.
The volume works as well

Thank you very much @eonpatapon for this wonderful extension, It's beautiful.
