My viewport is shifting up (above the display screen), triggered by an try to scroll to prime.

Two movies:

1. Twitter bug:

After I click on the search icon on the underside nav bar, the highest nav and backside nav shift up; nonetheless, the web page beneath doesn’t transfer. The result’s a distorted viewport.
