keep-alive include will also cache anonymous components

[PanJiaChen]

Version

2.5.2

Reproduction link

https://jsfiddle.net/L613xva0/13/

Steps to reproduce

triggle the route

What is expected?

the second route component not be cached

What is actually happening?

the second route component be cached

---

this demo tow router-view component both have name, the result is right ,
but in this demo, the second route have no name ,but also be cached

The match is first checked on the component’s own name option, then its local registration name (the key in the parent’s components option) if the name option is not available. Anonymous components cannot be matched against.

<keep-alive :include="cachePages">
  <router-view></router-view>
</keep-alive>

when l keep-alive router-view , every anonymous component page will be cached , i don't think is reasonable.

@yyx990803 Now keep-alive will not cache any anonymous components without include prop,it's a bug or a break change?

The same as @yuu2lee4.

You can see the reproduction in the console panel of this link https://jsfiddle.net/tqfc2edq/

The vue version 2.5.6, and you can see without "include", all anonymous components can't cahce. only mounted , without activated.

@yyx990803 but what if I need to cache anonymous component, how can I do that? There is no way? Why not to stick with the key passed to it? For example for that case I would expect this component working under keep-alive:

But it doesn't. Because it has no name.
