The Sky Nav should animate open/closed at smaller viewports

Regression?

Left: https://cloudfour-patterns.netlify.app/iframe.html?args=&id=components-sky-nav--dark&viewMode=story
Right: https://c4dev.wpengine.com

Notice on the left how the content below the nav also animates down/up.

Notice on the right how the content snaps down/up instead.
