In desktop, the top url-bar and other toolbars has a sharp border separating them from the webpage. This makes it feel like, the page is "contained" in a frame (provided by the browser). The page scrolls "inside" the frame. In latest nightly, with a change from bug 810278, the scroll behavior is changed. 1. The depth of field (provided by dark black) is lost. 2. Instead, the page feels like a post-it note on top of the browser frame. 3. Browser loses the affordance of a frame. 4. The page (sticking on top of the frame), is casting a shadow on the browser. 5. When this scroll down, the entire page scrolls down "over the frame". 6. When this scroll up, it is limited by the browser's frame. This behavior is so weird. Ideally if the page should be sticking over the browser frame, it should scroll over the url-bar. But we can't do that. Hence, it should be "contained" in the browser frame. The depth of field and the shadow should be preserved. The browser is now spatially challenged.

Let's wait for that and see how all these elements play together when that's working.
