--build attached scene
--copy attached indexiframe.html into build folder
--start indexiframe.html
--try typing when it finished loading

--add the following snippet to the index:
<script>
window.onload = function() { window.focus(); }
</script>
--load indexiframe again
--try typing when it finished loading
--notice you see stuff being typed in the scene
