It's broken the same way in the non-tiled version too as far as the repainting is the concerned after the style change. However, since non-tiled scrolling involves repaints as you scroll (no pre-painted buffers), the out-of-the-viewport part gets repainted and that fixes the background color. If you scroll to the bottom first and reload the page, you see the broken background color (and gets cleared up right after the document is scrolled)
