Introduced in version: 1.3 (29 Jan 2020)
When list operations “Change list/Remove”, “Change list/Replace”, “Union”, “Intersect” “Subtract”, “Contains” or “Equals” are called with the same list for both arguments then the result is trivial.
For example, when doing a union of a list with itself the result is the same list. When checking if a list contains itself the result is always true. When removing a list from itself the result is an empty list.
This is most likely a bug and some other argument was intended to be passed.
