Keyboard shortcut 's' no longer works as it did.
Previously it would mark all items in a folder read and skip to the next folder.
Now the unread counter on the folder is cleared, but it does not skip to the next folder and items are still marked unread. Manually switching between folders shows the items no longer are marked.
