test case

REPORT:
iOS (15.3)

Although focus({preventScroll: true}) is supposed to be supported on iOS, it doesn't seem to have any effect. As you can see in the test case, when scrolling the input out of view and clicking the button to focus it, it scrolls into view, where-as scroll should not be affected.

This works as expected on MacOS.

Feature implemented last year in ticket https://bugs.webkit.org/show_bug.cgi?id=178583
