Steps to reproduce

1. Open the minimal reproduction and open the Console panel in the browser developer tools.
2. Click the user radio input.
3. Within 5 seconds, switch back to the about radio input.
4. Wait for 5 seconds.
5. Click the +1 button.
6. At this point, the Console will show:

[About.vue] number updated 1
[User.vue] number updated 1

What is expected?

Only the watcher callback in About.vue should run after clicking the +1 button. User.vue should not log any update because the view has already been switched back to about.

What is actually happening?

[About.vue] number updated 1
[User.vue] number updated 1
