Call update on render when component is not in DOM

[dy]

I was playing around with nanocomponent and component-box as possible target solution for jsx compilation and stumbled upon an issue.
Sometimes we may expect updaing a component state by calling render, even when the component is not in the DOM, eg.

let menu = new Menu()

// these render calls do not incur update call
menu.render({ content: 'Home' })
menu.render({ content: ['A', 'B'] })

document.body.appendChild(menu.render())

Does it make any sense to invoke update even for detached components? We can imagine some components not dealing with DOM at all.
