FWIW this is the same test that was causing the assert issue we saw on the tracked props PR. For some reason, when running all of the tests, by the end of this test Ember.assert would be stubbed and wouldn't go back to normal. This was only if you ran all of the tests.

Rebased, hopefully I had just not included that Edge Ember.assert reset fix you did. 🤞

Eeck. I completely forgot about this 😩. Rebased and updated to BUGFIX release.
