GoRead seems to get confused when using j/k to read#339

When reading articles using j/k to scroll through, I often notice that goread appears to mark all unread articles as read in the left nav, and subsequent presses of j/k dont work. When I re-click on the articles, sometimes my position has changed, but I see that the unread articles remain in the main view. I realize this is confusing to describe, I'd be happy to elaborate further if needed (and this isn't a KI). Thanks!
