This error occurs on the third render. The count reaches 2, then throws:

[Error] TypeError: number is not iterable

import { html, signal, render } from 'https://esm.run/uhtml/auto';

let count = 0

const root = () => html`
  <p>count is ${count}</p>
`

setInterval(() => {
  count++
  render(document.body, root)
}, 1000)
