Workaround for ios 11 bug

[jhubble]

The code causes the iOS 11 keyboard to overlay an input field, making it impossible to see what is being typed. Commenting it out fixes the issue.

@Christilut See my comment about this. The code this pull request removes reopens a serious issue.

This also works:

// prevents scroll-position jumping
            overflows.forEach(function (el) {
                if (el.node.scrollTop !== el.scrollTop) {
                    el.node.scrollTop = el.scrollTop;
                }
            });
