Taskboard thinks it is on page 2 after closing an iframe window

After opening the iframe of a task on the taskboard, when closing triggers a refresh of the taskboard, the pagination control thinks it is on page 2 when in reality it is still on page one. Hovering over page 2 doesn't open the hints, but hover over page one shows all the stories/tasks currently seen and you can't click the "2" to get to page 2.
