React version: 16.12.0

Steps To Reproduce

A component that suspends as a result of a context update is never rendered to DOM after suspension is finished.

The current behavior

If a component suspends as a result of a context update, the component's render is called after suspension is finished but the result of the render is not reflected in the DOM (and effects aren't called).

The expected behavior

If a component suspends as a result of a context update, the component's render should be called and flushed to the DOM and effects called.
