Copy Contribution Page does not copy associated quick-config price set

From Manage Contribution Pages - select 'more' -> 'Make a Copy'. The contribution page is copied but the quick-config price set is not copied. This means the associated fee amounts are lost and the copy is not usable (when you look at the 'Live Page' there are no inputs for contribution amount(s) ).

The copy action should create a copy of the quick-config price set, price fields, price field value rows and insert a new row in price_set_entity.
