iframe has scrolling="no"

We use requirebin to teach some young folks javascript.
When the preview iframe visualizes a lot of things, it would be nice if it was scrollable.
Is the scrolling="no" on purpose?

I guess it is happening here:

i think the idea was when you embed it, it is weird if when you scroll down the page the iframe captures your scroll action from the parent page. but i can see the use case for it being disabled, we could have a querystring option that sets scrollingDisabled: false maybe?

that would be great :-)
We were manually copy&pasting to the dev tools to enable the wished for behavior.

document.querySelector('.play-button').addEventListener('click', function (event) {
  setTimeout(function () {
    var iframe = document.querySelector('iframe')
    var parent = iframe.parentElement
    parent.removeChild(iframe)
    iframe.setAttribute('scrolling', 'yes')
    parent.appendChild(iframe)
  }, 500)
})
