ling1726 d9c4920e8b fix: restore selection should consider the window of the container (#30951)
## Summary


Fixes #30864 

Before this PR the active elemen was always taken from the global
`window`. This is incorrect if the renderer is in one window rendering
into a container element in another window. The changes in this PR adds
another code branch to use a `defaultView` of the container element if
it exists so that `restoreSelection` after a commit will actually
restore to the correct window.

## How did you test this change?

I patched these changes to the repro repo in the linked issue #39864
https://github.com/ling1726/react-child-window-focus-repro/blob/master/patches/react-dom%2B18.3.1.patch.

I followed the same repro steps in the linked issue and and could not
repro the reported problem. Attaching screen recordings below:

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);
    },
    // ...
  });
}
