Ember Model Fragments Freezes Chrome DevTools/Ember Inspector

Versions:
Ember Inspector: 2.1.1 (up to date)
Ember: 2.13.1
Ember-Data: 2.15.0-beta.1
jQuery: 3.2.1
Ember Bootstrap: 1.0.0-rc.1
Model Fragments: 2.14.0

Steps to Reproduce:

1. Create a model with a fragment (example: Model: Person) with a fragment (PhoneNumbers).
2. In the app, load the models through the store.
3. Open your Chrome (Version 60.0.3, 64-bit) DevTools, navigate to the Ember tab.
4. In the Ember Inspector, select Data.
5. Select the model with the ember-data fragment (Person) and see that no data is displayed.
6. DevTools and the Tab are no longer responding, and must be closed.

Reproduce the issue with the listed Ember, Ember Data, Ember Inspector, jQuery, and Model Fragments versions by loading a Person model with a PhoneNumbers fragment. Open the Ember Inspector Data tab, select Person, and verify that the data appears without freezing Chrome DevTools; the payload names no source files or tests to inspect.
