iOS Safari/Chrome - Unwanted scrolling when focusing an input inside the modal
<p>Tested in Safari and Chrome - the same result, so I think it's iOS issue.</p>

<p>This happens only if there's an input inside the modal and I tap that input. In the same moment that input got focus and native iOS keyboard become visible. </p>

<p>Page below modal in the same moment is automatically scrolled to 50% of its height. This behaviour is totally unwanted and I have no clue how to prevent this default iOS "feature".</p>

<p>Demo:</p>
