True, but surely saying "any element" opens the door to full-screening inline text elements (e.g <span> elements).

Looking at a few lists of all inline elements in HTML, there aren't any except <img> (except perhaps form inputs/textareas) that should obviously be permitted this sort of full-screen capability (without first being defined as "display: block").

I suppose the native style being "position: fixed" would put those elements in a block formatting context anyway, but what implications might that have for things like table cells/table rows being made full-screen?
