Vue.js version

2.0.1

Reproduction Link

https://jsfiddle.net/uyt4tzak/1/

Steps to reproduce

1. Open reproduction link
2. Go to /auth/register
3. Play with step buttons, in console you'll see components are correctly activated/deactivated
4. Click on the login button, you'll be redirected to home view (/) and in console you'll see that Auth/Login/Register components are properly destroyed, except components inside Register component. Their destroyed hook isn't called.

What is Expected?

Dynamic component inside nested <keep-alive> component should be always properly destroyed.

In my case, after redirecting from /auth/register to / you should see following logs in the console:

Auth component destroyed
Login component destroyed
Register component destroyed
destroyed step X

What is actually happening?

Destroyed hook in Step component is never called, which means that component itself is never destroyed.
