Safari 10.1 fails differential loading browser test

[clydin]

Safari 10.1 is currently the only browser failing the newly added browser testing for differential loading. A newly generated application created from a master version of the CLI is used as the system under test.

The following error is generated upon execution of the application's E2E test:

undefined is not an object (evaluating 'd.prototype[b].apply')

Further investigation is required.
