+      // - and the info directive also has a transclusion-based directive at its root (transSync)
+      // In this scenario, the transcludeFn is not passed to the transSync nodeLinkFn at link time.
+      //
+      // (The trans directive is simulating what ng-if does, which is call its transludeFn during a
+      // subsequent digest if its value evaluates to true)
+      //
+      // If the trans directive is not async then the transcludeFn does get passed.
+      //
+      // In debugging you can see that the delayedNodeLinkFn is not passing the transcludeFn down
+      // to the afterTemplateNodeLinkFn
