Nuxt.js: Error page causes layout components mount twice

[gerasimvol]

Version

v2.11.0

Reproduction link

https://codesandbox.io/s/mounted-twice-error-page-f2qvy

Steps to reproduce

1. watch Console and see 'LOGO MOUNTED IN LAYOUT' from ~/components/Logo.vue used in ~/layouts/default.vue
2. click on 'error' link
3. observe 'LOGO MOUNTED IN LAYOUT' from Logo.vue again
4. navigate to any links and see no more messages

What is expected ?

'LOGO MOUNTED IN LAYOUT' message only once in console, because layout is not changing

What is actually happening?

'LOGO MOUNTED IN LAYOUT' message is shown twice, when visiting error page

Additional comments?

no such bug in 2.7.1 for example

Sorry for the delay @gerasimvol

When I go to https://f2qvy.sse.codesandbox.io/asdasdasd, I only see the log once in the console.

@Atinux I think it's because sandbox uses old nuxt version
I have locked nuxt to 2.11.0 - bug is present now
