Take this set of Nested steps for example
I copy it, and the Time in the copied Log Message action, comes from Step 3 instead of Step 4.
The engine knows the original mapping, when you have 3 or more steps which we can copy with 1 click, why should step 7 then refer to one of the fields within the first couple steps. It should refer to a field in step 5-6, otherwise, it's not a copy.
