You may have an infinite update loop in a component render function

Hi,

I'm experiencing an infinite update loop using a mixin, VueJs is warning me and breaking the app in dev mode.

Here is a reproduction : https://codesandbox.io/embed/vue-template-ndzlk

Am I doing something wrong or is there another way of doing it when using the router-multi-view component ? Everything works as expected if I'm using vue-router.

Best regards
