Say you have a PropertyDrawer for a type. When showing an array of this type in the inspector, the PropertyDrawer will be used on all the elements. The field PropertyDrawer.fieldInfo holds the reflection FieldInfo of the displayed field. Since array elements aren’t fields you can’t get the FieldInfo, so what is the PropertyDrawer.fieldInfo field for array elements set to?
I investigated it and the fieldInfo is just set to the FieldInfo of the array.
