Description of the bug

After applying the suggested access widener (AW) by MC-dev on members of outer class it stops suggesting to apply the AW. When I apply an AW to an inner class or the members of the inner class, MC-dev will keep suggesting to apply the AW.
Somewhat minimal code example to make clear what I mean:

// MC-dev suggests to AW ItemStatsListWidget, specifying the internal name results in mixin saying I can use the class Ref instead bc it is already public
@Mixin(StatsScreen.ItemStatsListWidget.class)
class ItemStatsListWidgetMixin {
    @Shadow @Final
    StatsScreen f_2839217;

    @Redirect(method = "<init>", at = @At(value = "INVOKE", target = "Lnet/minecraft/stat/PlayerStats;get(Lnet/minecraft/stat/Stat;)I")
    )
    public int init1(PlayerStats instance, Stat stat) {
       // Stats is a member on the outer class that is accessed through a synthetic field inside the inner class and this works fine and MC-dev doesn't keep suggesting to apply the AW after you applied it.
        return ((IPlayerStats) f_2839217.stats).bismuthServer$getLongStat(stat) > 0L ? 1 : 0;
    }
}

@Mixin(targets = "net/minecraft/client/gui/screen/StatsScreen$ItemStatsListWidget$1")
class StatComparator {
    @Final @Shadow
    // Outer class
    StatsScreen f_5153485;

    @Final @Shadow
    // Inner class
    // synthetic field, MC-dev suggests to AW ItemStatsListWidget
    StatsScreen.ItemStatsListWidget f_7207520;

    @Inject(method = "compare(Lnet/minecraft/stat/ItemStat;Lnet/minecraft/stat/ItemStat;)I", at = @At(value = "INVOKE", target = "Lnet/minecraft/stat/PlayerStats;get(Lnet/minecraft/stat/Stat;)I"), cancellable = true)
    public void compare(ItemStat itemStat, ItemStat itemStat2, CallbackInfoReturnable<Integer> cir, @Local(ordinal = 0) Stat stat, @Local(ordinal = 1) Stat stat2, @Local(ordinal = 0) int i, @Local(ordinal = 1) int j) {
       // Access of member on outerclass is fine (and MC-dev only suggests AW till you apply it) : 
       f_5153485.stats;
       // Access of member on inner class MC-dev keeps suggesting to apply the AW
       f_7207520.f_2401102;
    }
}
