Viewport Fill Opacity Attribute

The root SVG element of this test slide has a 'viewport-fill' attribute set to 'yellow' with a 'viewport-fill-opacity' of 1. At the start the entire background should be solid yellow. This should then change to a pale bluish gray. There are two reference squares in the center - solid yellow - to match the background at the start and a pale yellow that should match the backgound after a few seconds.
