Description
Demo:
const s = signal(0);
function inc() {
s.value++;
}
export default function App() {
return html`
${s}
<button onclick=${inc}>Increment</button>
`;
}
When "Highlight updates" is enabled, I would expect the number to be highlighted every time it changes because I click on the button.

Research direction
Start by running the supplied signal-based demo in the Preact DevTools extension with “Highlight updates” enabled, then trace how signal-driven text-node changes are detected. Done means the rendered number is highlighted after every button click, with the behavior checked against the provided reproduction.
