playground hangs indefinitely with keep-alive and missing adjecent v-if combination about repl

[linpeng118]

Hello,
First of all this is the place to solve the problem of @vue/repl, your problem is not about repl. Then you're not familiar with keep-alive.
the right way:
<keep-alive include="a,b"> <component :is="view"></component> </keep-alive> or <keep-alive> <router-view v-if="$route.meta.keepAlive"></router-view> </keep-alive>
Thanks.

The repro has an intentional "bad" code.
To trigger the playground freeze.

Same code should show errors in regular vue build
