In MB the behavior of the stars is different everywhere.
The track list is not selected stars are not visible at all, and when you hover they don't light up, in the "Track information" they are visible but does not light up when hovering;
The desired behavior is editing tracks, not marked by stars are visible, and when you hover they light up;
Very inconvenient to aim for the star when it is not visible and when it is not illuminated, and the unification never hurts.
Sorry for my bad English.
