Restyle the notification bubbles on review requests.
Review Request #7281 — Created May 2, 2015 and submitted
This improves the look of the review request update notification bubbles. The top-left corner is rounded, there's slight shadow, and the bottom and right edges are now flush with the edge of the browser viewport.
Triggered a notification bubble and saw the style.
