Blocked updates when using router and styletron plugins

[KevinGrandon]

Type of issue

Bug

Description

Including the fusion-plugin-styletron-react plugin will block react router updates occasionally.

Current behavior

I'm still working on a STR here, but it seems that including fusion-plugin-styletron-react will cause the router plugin to stop working. Links can be clicked which will update the browser URL, but the component does not render.

It feels like a symptom of: https://github.com/ReactTraining/react-router/blob/master/packages/react-router/docs/guides/blocked-updates.md

Expected behavior

Everything works as normal.

Your environment

I'll try to implement a minimal reproducible repository.

Interesting note:

This reproduces with code like:

app.register(Styletron);
app.register(Router);

If you simply swap the order, the issue goes away:

app.register(Router);
app.register(Styletron);

I think this has to do with: remix-run/react-router#6072
(Styletron uses React.createContext API in React 16.3 via create-react-context)

Should be resolved in React 16.4
