| This test ensures that autoscrolling doesn't scroll an iframe that's marked |
| as unscrollable via `scrolling="no"`. To test manually, fully scroll the blue |
| inner scroller and use middle click autoscroll (Windows feature) from the |
| inner blue scroller or the rest of the iframe to scroll downwards. This test |
| passes if the iframe that contains the blue scroller doesn't scroll. |
