Yes, we're aware, but there's some discussion to be had about which way is correct...
If a user defines a binding on an element of a list, do we assume they're applying the binding to the element/object and that binding should move if other elements are inserted? Should the binding always be on that index of the list, even if other elements are inserted/removed?
Many are quick to respond with "I want the binding on the element", BUT there's every possibility that the list is also mutated/modified through scripting, and there's no way to for us to update the binding in that instance.
