Added a regression test and verified it failed before the fix.

<summary>facebook/react</summary>

### [`v16.4.0`](https://github.com/facebook/react/blob/master/CHANGELOG.md#&#8203;1640-May-23-2018)
[Compare Source](facebook/react@8e5f12c...v16.4.0)
##### React

* Add a new [experimental](`reactjs/rfcs#51) `React.unstable_Profiler` component for measuring performance. ([@&#8203;bvaughn] in [#&#8203;12745](`facebook/react#12745))
##### React DOM

* Add support for the Pointer Events specification. ([@&#8203;philipp-spiess] in [#&#8203;12507](`facebook/react#12507))
* Properly call `getDerivedStateFromProps()` regardless of the reason for re-rendering. ([@&#8203;acdlite] in [#&#8203;12600](`facebook/react#12600) and [#&#8203;12802](`facebook/react#12802))
* Fix a bug that prevented context propagation in some cases. ([@&#8203;gaearon] in [#&#8203;12708](`facebook/react#12708))
* Fix re-rendering of components using `forwardRef()` on a deeper `setState()`. ([@&#8203;gaearon] in [#&#8203;12690](`facebook/react#12690))
* Fix some attributes incorrectly getting removed from custom element nodes. ([@&#8203;airamrguez] in [#&#8203;12702](`facebook/react#12702))
* Fix context providers to not bail out on children if there's a legacy context provider above. ([@&#8203;gaearon] in [#&#8203;12586](`facebook/react#12586))
* Add the ability to specify `propTypes` on a context provider component. ([@&#8203;nicolevy] in [#&#8203;12658](`facebook/react#12658))
* Fix a false positive warning when using `react-lifecycles-compat` in `<StrictMode>`. ([@&#8203;bvaughn] in [#&#8203;12644](`facebook/react#12644))
* Warn when the `forwardRef()` render function has `propTypes` or `defaultProps`. ([@&#8203;bvaughn] in [#&#8203;12644](`facebook/react#12644))
* Improve how `forwardRef()` and context consumers are displayed in the component stack. ([@&#8203;sophiebits] in [#&#8203;12777](`facebook/react#12777))
* Change internal event names. This can break third-party packages that rely on React internals in unsupported ways. ([@&#8203;philipp-spiess] in [#&#8203;12629](`facebook/react#12629))
##### React Test Renderer

* Fix the `getDerivedStateFromProps()` support to match the new React DOM behavior. ([@&#8203;koba04] in [#&#8203;12676](`facebook/react#12676))
* Fix a `testInstance.parent` crash when the parent is a fragment or another special node. ([@&#8203;gaearon] in [#&#8203;12813](`facebook/react#12813))
* `forwardRef()` components are now discoverable by the test renderer traversal methods. ([@&#8203;gaearon] in [#&#8203;12725](`facebook/react#12725))
* Shallow renderer now ignores `setState()` updaters that return `null` or `undefined`. ([@&#8203;koba04] in [#&#8203;12756](`facebook/react#12756))
##### React ART

* Fix reading context provided from the tree managed by React DOM. ([@&#8203;acdlite] in [#&#8203;12779](`facebook/react#12779))
##### React Call Return (Experimental)

* This experiment was deleted because it was affecting the bundle size and the API wasn't good enough. It's likely to come back in the future in some other form. ([@&#8203;gaearon] in [#&#8203;12820](`facebook/react#12820))
##### React Reconciler (Experimental)

* The [new host config shape](https://github.com/facebook/react/blob/c601f7a64640290af85c9f0e33c78480656b46bc/packages/react-noop-renderer/src/createReactNoop.js#L82-L285) is flat and doesn't use nested objects. ([@&#8203;gaearon] in [#&#8203;12792](`facebook/react#12792))
