What steps will reproduce the problem?
1. Open a large code review and scroll down a few pages via the page-down key.
2. Try to scroll via the up or down arrow.
What is the expected output? What do you see instead?
I'd expect the screen to scroll immediately. Instead, it just moves the horizontal marker, which is invisible as it's several pages up, so it seems like nothing happens. This probably broke at https://code.google.com/p/rietveld/source/detail?r=140baeb01745, just like https://code.google.com/p/rietveld/issues/detail?id=382, but I didn't catch it when testing the fix for 382.
I still find little value in the feature that caused the bug, and it slows down arrow-scrolling, but if you don't want to remove it, I suggest that you jump the horizontal line to its preferred location on the current screen when it's off-screen and an arrow key is pressed.
