fix(comments) Fix circular reference error

In Chrome, before sending a message it serializes the message object
with JSON.stringify, so not an actual reference going to be passed to
the listener.
JSON.stringify can not serialize circular references:
var a = [{v: 1}];
a[0].b = a[0];

This is not causing issue in Firefox
