Minimal reproduction of the problem with instructions

This was discovered when switching ng-bootstrap to Angular 4 rc.5. Here is a plunker that works with the latest 2.3.x but fails when switching to Angular 4 rc.5:

Steps to reproduce:

• hover over stars and mouseleave - see that the care comes back to the initial value
• switch to 4.0.0-rc.5 in the config.js and repeat the scenario - see that with 4.0.0-rc.5 rating doesn't come back to the initial version on mouseleave

You can see the code for the rating directive here: https://github.com/ng-bootstrap/ng-bootstrap/blob/master/src/rating/rating.ts

I'm working on a reduced reproduction scenario but wanted to open an issue ASAP as an "early warning". Currently my suspicion is that sth goes wrong when creating embedded views (or more precisely - refreshing them when context changes). I will provide a smaller reproduce as soon as I can narrow it down.

• Angular version: 2.0.X

4.0.0-rc.5

• Browser:
