Current behavior:
I have multiple inputs in a page, and I focus them manually every time using the setFocus() method. The problem is that when i do so, the page makes the correct scroll but when this scroll is finished it return to de no scroll position, is like something is cancelling the scroll. I have read a lot of issues of IOS keyboard and i still couldn't find exactly what the problem is.

In this gif is shown the current behaviour.

Expected behavior:

Of course the current behaivour would be that when focusing the scroll stays stable.

Solution?

In my case, wrapping the element.focus() with setTimeout solved the issue:

setTimeout(() => {
    element.focus();
});
