What is actually happening?

Caused by https://github.com/vuejs/vue-next/commit/f4639e0a36abe16828b202d7297e1486653b1217

Not limited to SSR apps.

We should find a way to skip this setTimeout, (or potentially the whole devtools setup call?*) when we are:

a) in running tests b) in jest c) in jsdom (detection)

*: we likely want to keep the devtools setup as we might want to use devtools for in-browser-tests - we should rather skip the setTimeout only.
