## Summary `FragmentInstance.blur()` only matched the active element against the first level of host children. If the focused element was nested inside one of those children, `focus()` could reach it but `blur()` would leave it focused. This treats an active element contained by a Fragment host child as part of the Fragment and blurs the active element itself. It also adds regression coverage for a nested input. Fixes #37124. ## How did you test this change? - `yarn test ReactDOMFragmentRefs-test --runInBand` (65 tests passed) - `yarn test --prod ReactDOMFragmentRefs-test --runInBand` (65 tests passed) - `yarn prettier` - `yarn linc` - `yarn flow dom-node`
react-dom
This package serves as the entry point to the DOM and server renderers for React. It is intended to be paired with the generic React package, which is shipped as react to npm.
Installation
npm install react react-dom
Usage
In the browser
import { createRoot } from 'react-dom/client';
function App() {
return <div>Hello World</div>;
}
const root = createRoot(document.getElementById('root'));
root.render(<App />);
On the server
import { renderToPipeableStream } from 'react-dom/server';
function App() {
return <div>Hello World</div>;
}
function handleRequest(res) {
// ... in your server handler ...
const stream = renderToPipeableStream(<App />, {
onShellReady() {
res.statusCode = 200;
res.setHeader('Content-type', 'text/html');
stream.pipe(res);
},
// ...
});
}
