test case

On a long page, when focus() is called on an element within an iframe, and if the offsetY of the iframe is > 0, the browser incorrectly scroll after the frame.
It occurs only on non-input HTML elements (like div or span with a tabindex attribute).

The same issue is observed when element.scrollIntoView() is called from an iframe.


I reproduced the issue on iOS (11.3.1), and with a locally built WebKit.




It's very similar to the following closed bug : https://bugs.webkit.org/show_bug.cgi?id=158629 .
