Do you want to request a feature or report a bug?

I want to request a bug.

What is the current behavior?

If we useContext inside Component in a custom renderer tree, the default value (value passed to React.createContext function) is returned.

What is the expected behavior?

Expected behavior is to get the latest value of the context.

Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?

react: 16.7.0-alpha.0
react-dom: 16.7.0-alpha.0
react-reconciler: 0.17.0-alpha.0
scheduler: 0.11.0-alpha.0

Here's a reproduction case https://github.com/HriBB/react-repro. Already filed related bug to react-devtools issue tracker.

This is an expected limitation. See #13336 (comment) for a workaround.
