focus property not working on HTMLInputElement

[mspoulsen]

import {
  div,
  DomSinks,
  DomSources,
  input,
  makeDomComponent
  } from '@motorcycle/mostly-dom';
import { now } from '@motorcycle/stream';
import { run } from '@motorcycle/run';


export function UI(sources: DomSources): DomSinks {
  const {  } = sources
  

  const view$ = now(view())

  return { view$ }
}

function view() {
  return div([
    input({
      className: 'fooClass',
      value: 'foo',
      focus: true,
      selectionStart: 2,
      selectionEnd: 3
    }),
    div('oooo')
  ])
}


const element = document.querySelector('#app')

if (!element) throw new Error('could not find element')

run<DomSources, DomSinks>(UI, makeDomComponent(element))

I would expect focus to be on the input field after rerendering, but it is not.
