Unstaged file's scroll position refreshes when a file is staged.

A user reported,

"The problem is that whenever I add something to the "Staged Files", the focus of the File Status view shifts to show that staged file. This becomes an issue when:

1) I am adding multiple but not all chunks of a file-to make this work, every time I add a chunk I have to relocate the file I am adding from and then the place in the file where I left off

2) when I am adding several files from a dirty workspace with a lot of edited files

In this case I have to scroll back through the "Staged Files" and "Unstaged Files" to find my old scroll position and continue evaluating the remaining unstaged files."
