Summary

When some complex cyclic JS object is passed, it doesn't show anything.

Details

data = {
    "_this": new AppComponent(), //<== cyclic
    "name":"AppComponent"
  };

Expectaion:
Either, library should ignore data._this or show it to some depth. In both the cases, library must show data.name which is a primitive.

Reality:
Nothing shows up
