- Full support for content projection in downgraded Angular 2 components. In particular, this enables multi-slot projection and other features on <ng-content>. - Correctly wire up hierarchical injectors for downgraded Angular 2 components: downgraded components inherit the injector of the first other downgraded Angular 2 component they find up the DOM tree. Closes #6629, #7727, #8729, #9643, #9649, #12675
