[React 19] dangerouslySetInnerHTML causes repaint #31660
Description
Summary
Given the following component
function App() {
const [count, setCount] = useState(0);
return (
<>
<button onClick={() => setCount((count) => count + 1)}>{count}</button>
<div dangerouslySetInnerHTML={{ __html: "I should only paint once" }} />
</>
);
}Clicking the button should not trigger a repaint of "I should only paint once". This works as expected in [email protected] but not in [email protected] or [email protected].
