[bugreport] Changing the artwork temporarily messes up the beatgrid

I've noticed that when you add / change the artwork of an mp3 file, it quite often moves the beatgrid.

Loading the song again fixes it so it is not too "urgent".

It doesn't happen always but quite often so it wasn't just one-off fluke either.

Version of rekordbox: 6.6.8
Laptop running it: MacBook Pro (14-inch, 2021), OS version 12.0.1 (21A559)

thank you :)
