Mobx: Upgrading mobx to 6.0.0 and mobx-react 7.0.0 not working

[DavisJaunzems]

I was trying to replicate simple mobx-react application using the Todo example. After spending some time I've realized that using mobx 6.0.0 together with mobx-react 7.0.0 is not working.

Intended outcome:

Working Todo example application

Actual outcome:

Not working after upgrading to mobx 6.0.0 and mobx-react 7.0.0

How to reproduce the issue:

I've created two sandbox environments where everything is the same only using different mobx and mobx-react versions:

Working: https://codesandbox.io/s/reverent-booth-ehmz0?file=/src/index.js
Not working: https://codesandbox.io/s/confident-cray-2wl0y?file=/src/index.js

Versions

Working: mobx "5.15.7" and mobx-react "5.4.4"
Not working: mobx "6.0.0" and "mobx-react" "7.0.0"

Please read release announcements or migrations guides first when bumping major versions. We write that stuff for a reason https://mobx.js.org/migrating-from-4-or-5.html / https://michel.codes/blogs/mobx6
