Additional CSS Classes not copied when Pod duplicated

[Digitale-Substanz]

When a Pod is duplicated using Pods Admin, the values of field 'Additional CSS Classes' in tab 'Advanced' are not copied to the newly created Pod.

I can confirm this is correct.

Duplicating the 'field' however, does copy the settings in Advanced, Additional CSS Classes, but Duplicating the Pod itself these settings are not copied.

Going to have to revert this due to #4202

We can't blindly give preference one way or the other.

1. If we're duplicating a Pod, we need the existing options to have preference so they're copied to the new Pod
2. If we're saving a field normally, we need the new options to have preference so they're changed
