*Steps to reproduce:*
# Open a Unity Project
# Open Undo History via Ctrl + U. Keep this open and viewable
# Create a new Animator Controller via Assets > Create > Animation > Animator Controller
# Create a new state with right-click > Create State > Empty
# Create a transition between New State and Exit by right-clicking on New State and clicking 'Make Transition' then dragging it onto Exit state
# Select the created transition
# Use the shortcut Ctrl + C to copy it
# Click anywhere on the Animator graph and either right-click > Paste or Ctrl + V to paste it

*Actual results:* Nothing appears to be pasted. However:
* Undo History has added 'Paste State Machine Data' to the history
* In the Inspector, the details of the pasted transition are written, even though it is nowhere viewable in the graph. The Inspector will say that it is a state between AnyState and the state the original transition went to (Exit in this case)

*Expected results:* One of two results is expected. Either, the transition is pasted fully and viewable in the graph, or they aren't able to be copied/pasted at all
