That style seems to have become fairly common, and it really does suck on small screens. What's worse is when you try to zoom in to make the text readable and suddenly the top banner takes over the entire screen.
Or when it moves at the wrong moment as you go to scroll/pinch and then counts it as a click and opens the new page. At the very least let me close the damned thing, I've seen and read it enough to interact. Now let me read the site.
Sorry about that! We'll get that fixed right away.
