Version

5.0.0-beta.1

Browser and OS info

Chrome 69 / macOS 10.13.6

Steps to reproduce

1. Enable strict mode in Vuex
2. Edit the state via devtools

What is expected?

The state should be changed without throwing an error (since we are manually and knowingly changing the value via devtools).

What is actually happening?

The state is changed, but Vuex throws an error:

Error: [vuex] Do not mutate vuex store state outside mutation handlers.

It's really only a minor annoyance – not sure if it this can be changed at all (or if it's worth the trouble).
