-                  This should also be predicated on the session being active...
-                  inactive sessions should not show this information,
-                  even if it remains on the model instance
+                  Two if's here because:
+                  1) Local proxy info is only relevant if the session is
+                     active or pending (aka isCancelable).  Once the session
+                     is canceled or in the process thereof, the local proxy
+                     may no longer be used.
+                  2) The session actually has proxy information associated
+                     with it.  It's possible for the user to start sessions
+                     from other devices (or even another tab), in which case we
+                     won't have the local proxy info available here.
