Previous/next article buttons do not work when filter by tag is active

If i have a list of articles, which i filter by a tag, then i open an article in the middle of the list. The previous and next button do not work with the filter then. They show the next/prev. article by date, but not from the filtered list but the list of all articles.

I also doubt these buttons make any sense anymore. I would like to remove them. If i scroll to the end of an article, i'll usually use the mark as read button. And this one moves me back to the article list after i push it. So the prev./next buttons are never used and clutter the interface only.
