Bug: ErrorBoundary remounts children when errors are caught

<!-- Please provide a clear and concise description of what the bug is. Include screenshots if needed. Please test using the latest version of the relevant React packages to make sure your issue has not already been fixed. --> In the `render` block of a `ErrorBoundary` component the `props.children` is remounted when `getDerivedStateFromError` derives a new state (or `componentDidCatch` sets a state). Is this a special case ? Setting the state in any other manner (e.g `componentDidUpdate` doesn't have this behavior). I don't see this behavior documented in the React docs. Thanks! React version: 18.2.0 (Happens on 17.0.2 as well). ## Steps To Reproduce 1. In the code example increment the counter past 5 and the child component unmounts and mounts, the child state also resets <!-- Your bug will get fixed much faster if we can run your code and it doesn't have dependencies other than React.
