Conditionally keep-alive component cache goes wrong when 'include' prop dynamically changes

[shidianxia]

Vue.js version

2.1.8 with vue-router 2.1.1

Reproduction Link

https://jsfiddle.net/shidianxia/ckj7xbqq/

Steps to reproduce

a -> b -> c -> Back (b) -> Back(a) -> b -> c -> Back(b)

What is Expected?

b is cached and enter into activated lifecycle
Component "a,b" Cached

What is actually happening?

b is cached but mounted a new one
Component "a,b,b" Cached

You might have wanted to mention that you change includeall the time. that looks complicated to track :D

@LinusBorg Yes,I'd like to cache the components so I can see the cached content when I hit the back button. But I want to destroy the last component in order to re-render it when I enter again.
I'm not sure if I had describe my situation clearly 😂
