Touchevents don't work correctly in iframes

Repo:

1. Unzip the attached files and serve them (or maybe they work from file:, I didn't test)
2. Open "outer-works-kinda.html" in Safari iOS
3. Scroll down, try to drag the green square in the yellow area  (this works)
4. Open "outer-broken.html"
5. Scroll down, try to drag the green square in the yellow area  (this does not work)

The only difference between the 2 files is in `outer-broken.html` these 2 lines exist

    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1" />

In outer-kinda-works they don't

Note: if you remotely connect desktop Safari to iOS Safari on "outer-broken.html" and turn on/off a few CSSs (meaning mark them as off then re-mark them as on so that nothing should have actually changed) eventually the page will magically start working
