Steps to reproduce

Check the playground example and observe that an error appears:

parentComponent.ctx.deactivate is not a function

What is expected?

Instead of an error, it should be switching to a view that says "foobar".

It shouldn't matter whether items is reactive or not.

What is actually happening?

An error breaks the app when App.vue attempts to unmount the Comp1 component:

parentComponent.ctx.deactivate is not a function

Wrapping the value of items in Comp1.vue with reactive(...) fixes it.

a workaround, see playground

const items = ref([
  { id: 1, name: 'test1' }
])

I searched for existing issues but couldn't find any. I guess I searched for KeepAlive instead of keep-alive? I guess I learned my lesson.
