Mark some previously-read items as starred, then turn on "Hide Read" and open the "Starred" feed. The "Hide Read" option remains checked, but read items are still shown. Toggling the "Hide Read" option off and back on will remove the read items.
The correct behavior is probably to disable the "Hide Read" option entirely for the starred feed. There's currently no way to star an article without opening it, so we normally expect all starred items to be marked as read.
