vuejs2 - Vue.js | Reactivity in nested Component not working as expected

Question

Using the Vue2 $emit/$listeners feature (I know $listener will be removed in Vue3), I have the following problem, see playcode.io.

Clicking a compObj toggles it. Only one compObj must be active.

compArr reacts correct. But only the watcher of the compObj reacts, which i value is set to 1. But why does no compObj react, which i values are set to 0?
