20: Update react monorepo to v16.4.0 r=renovate[bot] a=renovate[bot] This Pull Request renovates the package group "react monorepo". - [react-dom](https://github.com/facebook/react) (`dependencies`): from `16.3.2` to `16.4.0` - [react](https://github.com/facebook/react) (`dependencies`): from `16.3.2` to `16.4.0` # Release Notes <details> <summary>facebook/react</summary> ### [`v16.4.0`](https://github.com/facebook/react/blob/master/CHANGELOG.md#​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. ([@​bvaughn] in [#​12745](`facebook/react#12745)) ##### React DOM * Add support for the Pointer Events specification. ([@​philipp-spiess] in [#​12507](`facebook/react#12507)) * Properly call `getDerivedStateFromProps()` regardless of the reason for re-rendering. ([@​acdlite] in [#​12600](`facebook/react#12600) and [#​12802](`facebook/react#12802)) * Fix a bug that prevented context propagation in some cases. ([@​gaearon] in [#​12708](`facebook/react#12708)) * Fix re-rendering of components using `forwardRef()` on a deeper `setState()`. ([@​gaearon] in [#​12690](`facebook/react#12690)) * Fix some attributes incorrectly getting removed from custom element nodes. ([@​airamrguez] in [#​12702](`facebook/react#12702)) * Fix context providers to not bail out on children if there's a legacy context provider above. ([@​gaearon] in [#​12586](`facebook/react#12586)) * Add the ability to specify `propTypes` on a context provider component. ([@​nicolevy] in [#​12658](`facebook/react#12658)) * Fix a false positive warning when using `react-lifecycles-compat` in `<StrictMode>`. ([@​bvaughn] in [#​12644](`facebook/react#12644)) * Warn when the `forwardRef()` render function has `propTypes` or `defaultProps`. ([@​bvaughn] in [#​12644](`facebook/react#12644)) * Improve how `forwardRef()` and context consumers are displayed in the component stack. ([@​sophiebits] in [#​12777](`facebook/react#12777)) * Change internal event names. This can break third-party packages that rely on React internals in unsupported ways. ([@​philipp-spiess] in [#​12629](`facebook/react#12629)) ##### React Test Renderer * Fix the `getDerivedStateFromProps()` support to match the new React DOM behavior. ([@​koba04] in [#​12676](`facebook/react#12676)) * Fix a `testInstance.parent` crash when the parent is a fragment or another special node. ([@​gaearon] in [#​12813](`facebook/react#12813)) * `forwardRef()` components are now discoverable by the test renderer traversal methods. ([@​gaearon] in [#​12725](`facebook/react#12725)) * Shallow renderer now ignores `setState()` updaters that return `null` or `undefined`. ([@​koba04] in [#​12756](`facebook/react#12756)) ##### React ART * Fix reading context provided from the tree managed by React DOM. ([@​acdlite] in [#​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.
