Object as children does not show any error or warning

When an object is passed as children to be rendered there’s no warning or error and it doesn’t render anything. I’m not sure if the issue is related to preact or fresh.

Example code

const activities = [
  { id: "1", name: "Wake up", date: new Date() },
  { id: "2", name: "Eat breakfast", date: new Date() },
  { id: "3", name: "Go to work", date: new Date() },
  { id: "4", name: "Go to sleep", date: new Date() },
];

export default function Home() {
  return (
    <ul>
      {activities.map((activity) => (
        <li key={activity.id}>{activity}</li>
      ))}
    </ul>
  );
}

The rendering inconsistency is a bug in preact-render-to-string. See https://github.com/preactjs/preact-render-to-string/issues/245 for that issue.

#761 will fix this being silently ignored. Instead an error will be thrown / warning logged in the future.

@lucacasonato this should be published as part of preact-render-to-string 5.2.5
