# Summary

When using iOS VoiceOver with Safari/Chrome the `document.activeElement` is not pointing to a button that has the attribute `aria-haspopup` instead it returns the `body` element. Removing this attribute causes the the `document.activeElement` to point to the button.

I guess this issue might be a symptom of some other focus handling logic.

# Example situation

1. A button opens a modal/dialog. This element is recorded by using the `document.activeElement`.
2. Modal captures focus.
3. When modal is closed the focus is returned to the element that opened the modal.

If the button has the attribute `aria-haspopup` the `document.activeElement` points to `body` instead of the `button`.

Example codepen: https://codepen.io/aaronkala/pen/wvEmeZL

# Expected behaviour

The `document.activeElement` points to the `button` even if it contains the `aria-haspopup` attribute.
