Similarly, when zoomed	in and when the element of interest is:
 1. taking	over	the screen and,
 2. the viewable portion	of the element is less than 50%

The Intersection observer still considers the element	 as fully viewable.

On the desktop, the API behaves as expected.

This is WAI; from the draft spec:

"Root intersection rectangle is not affected by pinch zoom and will report the unadjusted viewport, consistent with the intent of pinch zooming (to act like a magnifying glass and NOT change layout.)"
