• What is the current behavior?

Currently resumeBootstrap causes ngUpgrade to crash, but pending #7603 it will work. However, as @gkalpak points out, the current solution causes modules provided to resumeBootstrap not to reach downgraded ng2 directives. There isn't a straightforward solution though, because if bootstrapping happens before the ng2 directives are downgraded then the app will crash, since the ng2 templates don't work in ng1. Since there isn't a clear solution, I've decided to move forward with #7603 and document the problem here.

• What is the expected behavior?

Mock modules passed to resumeBootstrap should affect downgraded ng2 directives
