Drag & Drop songs in a playlist to reorder it sometimes fails to call editPLC
From a few times I tried to reorganize a playlist, once I finished moving a karaoke, the playlist would update itself and revert back my change.
Apparently it happened to @Kmeuh too a few times.
It doesn't happen everytime, but when it happens it doesn't make the API call to reorder the playlist (I had a console.log placed in the editPLC function to verify that)
Maybe a problem with the UI, but this would need further investigation
