 Twenty Seventeen: Fix Customizer preview display issues in IE9

 IE9 doesn't understands `vh ` (vertical height) when inside of an
 `iframe`. Normally IE9 will understand `vh` as the vertical height
 relative to the viewport, but in an `iframe`, IE9 thinks the vertical
 height is relative to the size of the whole page. So this fixes that when
 the site is viewed in the Customizer preview – an `iframe`.

 Props laurelfulford.

 Fixes #38722.
