Example with a heater. But same problem with many other items.
1: Select a heater.
2: Set a property of the heater to a custom value such as 20°C
3: Press the copy button.
4: Click to place the first heater-copy somewhere
5: Click somewhere else to place a second heater-copy somewhere
=> The first heater copy now has the correct setting (20°C)
=> Bug: The second heater copy now has the default setting (30°C)
