Keybindings behave differently in filter view

[larsks]

I've noticed a couple of discrepancies in how things behave when using filters:

1. When in a filter view, using m to mark an item as read makes all the items disappear. That was surprising.

   

2. When pressing enter to view an article and then returning to the list view, the cursor position isn't preserved -- it always jumps back up to the very first item. That's annoying, particular if the list of filtered items is long.

I expected when I filtered and then did "Mark all Read" (Alt-M) that only the items that matched the filter would be marked read. However, all items were marked read. Think when a filter is set only items that match the filter should be marked as read.
