iPhone/iPad Safari scrolling from top problems

Problem
  • On iPhone/iPad Safari the slider in the top is jumping higher/lower during down scrolling.
Cause

When you scroll down on iPhone/iPad Safari, the bottom bar hides and the top bar changes its height to a smaller size. After this, Safari triggers a resizing event, which will resize the website, which will move it higher and change the position of the elements, which might make you think that the slider has a problem, but it doesn't.
