In the page editor, a selected component should always remain within view. That has been fixed for desktop browsers, but our current handling of scroll top in iOS is quirky.

We already have a scrolltop preserving mechanism in place that prevents the editor from jumping to the top upon selection, but it doesn't seem to work well with the fix provided in MGNLUI-3109.

A hint: in MGNLUI-3109 if there is no direct scroll parent of the selected element (the whole page scrolls) - we set the scroll top of an iframe document. In iOS that would have no effect - the scroll top of PE widget element has to be set (parent of iFrame).
