Fix #3253. Bug where duplicating elements with fillings incorrectly recreated fillings at the cursor (i.e. the cursor was used as a target destination).

Now, instead of trying to be clever and regenerating filling locations and opening types, we simply copy the existing scenario. This also means it'll be more stable for weird fillings coming from proprietary apps.
