jQuery is converting params of the documentSubmit event to plain objects

[lukejagodzinski]

Let's take for example the documentSubmit event with all it's parameters:

Template.Form.events({
  documentSubmit(e, tmpl, doc) {
  }
});

If using the Astronomy package, we would expect the doc to be instance of our class, let's say an instance of the Post class. However:

Template.Form.events({
  documentSubmit(e, tmpl, doc) {
    if (doc instanceof Post) {
    }
  }
});

The instance check will return false. jQuery is transforming a document to plain objects.
